For me MTH 2 rail track is a welcome addition.  The selection is limited but they will likely expand over time if the line is successful.  Having a competitor to Altas and the dealer network of MTH would mean easy easy access to 2 rail RTR track options. I've seen the Lenz track system and their doubleslip in person but no where else outside of their booths.
 
Regarding the European market I heard at York from MTH's own folks, they were overwhelmed by the demand.  An example I remember they spoke of is a european order would be 5-6x the volume of an equivalent US order and MTH would have to adjust and ramp up  production for that size.  
 
In someways they are helping to drive upgrades here in the US.  Good example of this if you recall is PS2.0.  Many have had issues with PS2.0 not being good for 2 rail since it only had DCS and no DCC and it also had problems with reversing loops.  I am almost certain that the 2 rail O scale market in the US is not sizable enough to warrant such an investment but because Europe demands it we benefit.  PS3.0 is now shipping in quantity we're here to take advantage it. My PS3.0 engine count is now 5.  I'm looking forward to the PS3.0 upgrades in 2013.

When finally released - what do you expect a PS3 aftermarket command control board will cost?

As a side note I have a set of 2 rail MTH Premier PRR F7's on order - they are still listed for Feb 2012 delivery on the MTH shipping schedule.  I hope they get the PRR unique details correct - especially the "passenger" style pilot the PRR standardized on for its EMD F and E units. Does anyone know if the 2 rail pilot be fixed to the body - or swing with the truck?  For several years I held out hoping for an AtlasO PRR F3 or F7 but just got tired of waiting.

Well, the ScaleTrax line was admittedly slow to catch on, but once a number of highly regarded hi-rail modelers started using it with great success (as evidenced in Rich Battista's videos and on this very forum, among other places) it began to take off.  It's a fairly comprehensive line already, and I imagine it will expand as acceptance of the line expands.

To be honest I feel like the ties and tie spacing look almost identical to the 3 rail scaletrax line.  I will keep my hopes up! I feel that this might be the perfect combination to get people over to the 2R side and maybe even convince people in other scales who couldnt stand the 3R, to make the jump! 

Hi all,

 

Back in December my crew and I built O and HO display layouts for MTH that were shipped to Europe for the Nuremberg Toy Fair.  MTH had not yet received sample shots of the 2-rail track, so we built the O layout with Lenz track.

 

 

 

Like the European 0 scale models, the Lenz and MTH 2-rail ScaleTrax are built to 1:45 scale rather than 1:48.  The tie spacing and the ties themselves are larger than Atlas track.  The rail is code 148, which in the larger scale represents lighter weight European rail.  The ties measure 2.295" L X 0.233" W, which scales to 8'7" L X 10.5" W at 1:45.  The tie spacing measures 0.310" or a scale 14".  That works out to about 2600 ties per mile.  In the UK prototype mainlines are usually built with 2640 ties per mile.  Continental European standards vary by country, but are similar.  The height of the ties, however, measures only 0.165".  This dimension is the same as Atlas 2-rail track.  Atlas, Lenz, and MTH track are a nearly perfect match for height and rail dimensions and are easy to mate if one chooses.

 

Lenz makes sectional curves in 36", 40.5", 65", and 69.5" radius.  All of their turnouts, including the double slip and curved turnouts, are #5's.  MTH is offering sectional curves in 36" and 22" radius.  I asked Mike Wolf about the unusually tight 22" radius curves.  He said their intention is to include them in 2-rail boxed starter sets with track and transformer.  I don't know about in Europe, but in the US I can't recall anyone ever offering 2-rail O starter sets with track and transformer.  At least not since WWII.  Obviously, any such sets will have to include relatively small prototype engines and rolling stock to handle the tight curves.

That shouldn't be a problem Ed.  My brother, Ted, bought a set of GN F7's in 2-rail.  They came with the correct passenger pilot for the Empire Builder, so they do have the correct tool.  All the items cataloged to date as 2-rail have come with fixed pilots and Kadee mounting pads.  Only the bottom two rungs of the engineers ladder are still mounted on the truck.  All the F-units now have scale wheelbase trucks.

I just realized you had track and transformer but Atlas did try with track and train (no transformer) back in 2006/2007.  http://www.atlastrainman.com/Trainsets/otrainsets.htm

Mr Hikel, you have led a sheltered life.  Here's a short list of 2 rail 0 starter sets with track and transformer for the North American market that come to mind [ additions / corredtions welcomed ]:

 

1. The Kusan K series sets, circa 1958:  These were the 'all plastic' sets with the Alco cab;  Pittman motor, traction tires, DC, operating on 22" radius track.  And from the same company that pioneered 2-3 rail compatible locomotives, how could you forget....

2.  The 'old Atlas' sets, the ones with the F9

3.  The AHM sets, the ones with the C-liner or the 4 wh Plymouth

4.  Didn't ETS at one time offer 2 rail sets in the US with a transformer ?  They certainly did/do in Europe.

 

Currently in Europe the Lenz start set is offered with or without a 'transformer' [ eg, DCC base station ].  Historically Rivarossi and Lima offered sets with track and, in lieu of transformers, a battery pack.  As these mfgs mentioned the possibility of outdoor usage, that may have been the logical choice.  [ It's not clear to me if Pola-Maxi sets ever had a power source.]

 

The Atlas, AHM, and Lima sets came with 24" R curves;  Rivarossi, 32".  I think Pola sets started with the Riv. curves, and then switched to the 24" [ which they were also making for AHM anyway ].

 

With the exception of the Lenz sets [ and the ETS if my memory has failed me ], all of the above could be seen at past Yorks.

 

Best regards, SZ

 

Edited to add:

   I also think it's a little misleading at best to say that the Lenz curved turnouts are #5's;  might it not be better to say that their geometry is designed to work with, inter alia, the #5's ?  Since the inner radius of the Lenz curved turnout is [ only, unfortunately ] 41", that would be equivalent to about a #4.5;  I think a #5 is about 52" equivalent radius.

   I have one of the Lenz slips, and the workmanship / engineering are pretty darn good.  Unfortunately I don't have it on the layout yet [ I thought it might work in a throat area I was rebuilding, but that was set up for #6's or larger, and it just 'didn't fit in'.  Perhaps whenever I get to building the "parcel post annex"....]

Lenz track

 

Don't see a lot of application for the curve track IMO, but the  #5 turnouts and slip switch tight curved turnouts will work out in many freight track configurations.

 

Do not believe this  chart is new.  Seem to remember coming across this page years ago.  tt

Hi all,

Thanks Steinzeit, good to know.  The Kusan, old Atlas, and AHM sets are before my time and I don't recall seeing any complete sets at York or O Scale West in the years I have attended.  Nor do I recall any 2-rail box sets at the ETS booth at York.  They may well have imported some to their dealers.  They have set up some of their 2-rail tram equipment at York, but I don't recall seeing any box sets.

 

My main point is that there has been a dirth of 2-rail O scale starter sets.  For those of us already immersed in the hobby that can seem like trivial concern.  It's highly unlikely that anyone on this forum would be attracted to purchase a set because of the track and transformer.  However, for those looking at model railroading for the first time, the lack of an "all in one box" path of entry is a real obstacle.  A hobby shop has a much easier time selling these folks a 3-rail O or HO set.  Having a major manufacturer offering complete starter sets should be a good thing for the future of 2-rail O scale.

 

I also think it's a little misleading at best to say that the Lenz curved turnouts are #5's;  might it not be better to say that their geometry is designed to work with, inter alia, the #5's ?  Since the inner radius of the Lenz curved turnout is [ only, unfortunately ] 41", that would be equivalent to about a #4.5;  I think a #5 is about 52" equivalent radius.

 

It's not at all misleading.  Switch numbers are not determined by the internal radius.  They are determined by the departure angle of the diverging route.  The diverging route of a #5 switch diverges by 1 inch for every 5 inches of distance down the track.  That equates to an angle of 11.31˚.  All of the Lenz turnouts are built with a departure angle of 11.25˚; a fraction larger than #5.  While the NMRA's RP12.1 may advise a 52 inch radius for the curved potion of a #5, it is only a recommend practice, not a standard.  I certainly agree that wider radius is better, but that doesn't change the defining characteristic of a #5 turnout.

If I may offer my unlettered ramblings,

 

Setup:

 

On real railways most of us are aware that frogs are usually on a short section of tangent to ease frog picking by the flange.  However on some relatively tight curves I have seen frogs fabricated with a curvature especially with subways and trolleys.

 

In the model world, working with OP on curved switches Tim was able to use Lou's frog castings for the large radius curved turnouts but on the 50" / 60" radius curved custom switches the straight frogs just could not be made to fit so Tim rolled rail to assemble the frog.  The same way the Fast tracks videos demonstrate curved frog construction.

 

If you look at the turnout chart of OP & BK industries you will see non curved turnouts listed with their diverging ratio number.  With the curved turnouts you will see them listed as to radii of curvature.

 

When measuring any turnout with a constant curvature leaving the points  such as the typical three rail traditional "switch tracks" they are not listed as #___.  Rather they are listed, as we are accustomed with 0 scale curved turnouts, by their diverging radius.

 

When attempting to apply numeric designation to any turnout with one or both diverging tracks curved we can wind up tripping on our shoestrings.

 

I do not believe it accomplishes anything to apply a numeric frog angle ratio to curved switches in model railroading.

 

For the sake of a discussion, if a frog angle of curved turnouts is desired to be ascertained.  IMO. the area used to designate the ratio would need to be kept within a predetermined short set distance. Other wise as the curve continues the ratio would further demonstrate why numeric classification is not used for curved turnouts.

 

What screws everything up is the gray area of when is a turnout is of  a very wide radius with a close difference curvature such as a 225" / 229" curved turnout as used in a single cross over on a model RR.  Also bear in mind this single crossover turnout assembly in 0 scale is shipped in a container almost five feet long. 

 

Something helpful to bear in mind.  All the turnouts we folks use for our big mainline RRs, the #8s and #10s, they are actually sharper than many real life traction lines. 

 

Many mainline turnouts (#22, #24, #26)  would not even fit on the footprint of the average real life house lot many live on.

Jim, if the information I heard is true (2-sources) the 3-way and curved turnouts from Lenz will be here this summer.The Lenz turnouts are not cheap but next to Atlas they are of better quality....

      The Lenz number 5 turnouts are not curved through the frog (or after). 
      They are a true number 5.  See photo (double slips are Lenz, others are

       I have the same information. 

BTW, It is not important but for a time Atlas O and Weaver Models around 10 years ago offered 2 rail O Scale train sets but I am not sure they included track.  The original Atlas O scale line in the early 70's also offered 2 rail boxed sets with track and an HO size transformer.

 

AHM/Rivarossi also offered O scale sets with track and HO size transformers around 1969/1970.  I remember purchasing 2 sets in Woolworth's after **** at half price in Boston.  AHM advertised these in RMC about that time so someone can look it up if interested. I resold these items years ago.

 

Finally in 1949 General Models marketed 2 complete O Gauge kit outfits with track, loco and cars.  Quite a bit of assembly was needed though.

Certainly -- that wasn't in dispute.  "....the Lenz turnout..." in question is their curved turnout, which Mr Hikel thinks is [ also ] a #5.  See my April 27 post.
Best rgds, SZ   [ still semi-patiently waiting for the Lenz 4yg psgr cars ]  

Stienzeit,

 

I suppose we will have to wait until the curved switches are produced to know for certain that they will be #5's.  However, Lenz's literature describes them as having an 11.25˚ frog angle and an interior radius of 40.5 inches.  Assuming they curve all components of the turnout, as is done with other commercial curved switches, the outer radius will need to be just over 72 inches to be a true #5 curved.  Lenz hasn't cataloged any sectional curves that large, but they have cataloged their R11 curve at 69.5 inch radius.  If they use that for their outer curve it would be closer to a #5.5, but would still round to a #5.

 

Curved switches are a bit of an odd duck when it comes to switch numbering.  The frog and departure angles are determined by the difference in radii of the two curves.  It is mathematically possible to build a #20 curved turnout with impossibly tight curves.  You'll note that in RP12 the NMRA gives example dimensions for #4, 5, and 6 turnouts all built with an internal radii of 83 inches.  Obviously they are not implying that a curved switch with different dimensions couldn't or shouldn't be built.  Again, it's an RP, not a standard.  They simply offer them as examples of a curved turnout that would meet the numbering system.  It's up to the modeler to know the radius requirements of his equipment when considering such a switch.

Mr Hikel:

  1.  I've not seen anything in Lenz literature [ of the electric version ] that gives the frog angle, just the "angle of departure" [ as you use the term ].  Where specifically has Lenz quoted the frog angle ?

 2.  Yes, the frog and departure angles -- you admit they will differ for a curved turnout -- are determined by the combination of the two radii.  I said that a few days ago.  

 3.  The dimension of 83" [ the dimension in Row 6 of 12.1 ] is only the radius of the switch points [ blade ] and diverging stock rail opposite themselves.  Beyond the pivot points, the figures in Row 11 apply, and for #'s 4, 5, and 6 turnouts, those radii dimensions are 30", 52", and 83".

[ I'm not sure if you understand that RP.x is using the phrase "curved turnout" in a different sense than we have used it in this discussion ?  See para 4 of RP12 itself ]

 

To reiterate my original point:  To call a turnout with a diverging radius of 40.5" a Number 5 is quite misleading, because a modeller who knows the radius requirements of his equipment, and knows they will go through a conventional #5 [ = 52" curve ], may be in for a disappointment.  This would apply even if the Lenz curved turnouts had a #5 frog; the frog angle itself is moot, as is the "angle of departure".
