UP GE #2 diesel steam turbine 2+C-C+2 just assembled and tested.

Yard test video:

The turbine is very loud, just like the 'full size' one!

BEFORE:

When I acquired it, it had been sitting in the original box since the 70's, never opened.

AFTER:

Wow. It not only looks great, but runs smoothly and quietly, unlike some brass.

I have admired the 2 prototypes of these steamers for years.

I'm jealous.

Oddity. 2-6-4, scratch built by somebody, excellent workmanship, unfortunately mounted on an AHM chassis or partial chassis, emulates the esthetics of a PRR Q-1 4-6-4-4, may be 17/64 scale.

Plenty of room for a 4-wheel pilot truck - so why not a 4-6-4?

DSCN7923

Very strange cab floor - supported by 2 brake cylinders....? Partly it's the angle of the photo, but this rear view shows how tall the loco is, which made me wonder if the builder was going for 17/64" scale, rather than 16/64 (1/4)" scale. A 4-wheel front truck and a decent 6-driver chassis would make this a striking piece.

Looks like a Keystone number plate on the front of the smoke box (at least it looks like it from the one photo showing the front), you have the round PRR cab windows... Very nice!

It does indeed have a keystone - I should have gotten a pure head-on shot (maybe I will later). I have thought about attacking it and trying to put a better "driver section" under it, plus a 4-wheel pilot truck, yielding a streamlined "Pennsylvania Hudson", but I'm not sure that is legal.

Not only legal but would be placed in the P class of locomotives.  PRR always needed proper P1-P4 locomotives to get the P5 electric.  I think it is a cool build.

It is vaguely similar the PRR's K-4 Streamlined engines.   If you do make it into a streamlined Pennsylvania Hudson, just say it is one of Pennsy's many one-off experimental engines.

SP&S Z-8 4-6-6-4 Key 48

Annoying photo. Why, you ask?

Several years ago I bought a brass, lightly-used 3rd Rail/Sunset GN Z-6 Challenger. I have 072 curves on my 3RO Hi-rail layout, so big 3RO steamers can be accommodated.

However, there is one group of 3 switches, next to a curve, at the west end of the layout, and along the wall there, that I discovered cancelled the use of this loco on my railroad. Why? That long, long smokebox often used in lignite ("brown") coal-burning locos was incapable of getting past the "sky" at the curve. The building would have had to be lengthened a couple of inches, or a hole dug in the wall, maybe, to allow me to run this loco, and the curve/switches could not be changed without changing the entire world.

So I sold the loco. She no fit the architecture. The Clinchfield Challenger, Southern 2-8-8-2, USRA 2-6-6-2 clear just fine.

You're 'right' about that.

A lot of people think the UP 4-6-6-4 challenger is the largest challenger even though they were the first with it's design:

The UP challenger has that big 'porch' on the front so it's boiler is not as long as the NP/GN Z-6's and Z-8's.

UP 4-6-6-4 1999 299

The NP/GN boilers 'fill up' that 'porch'.

Idiots like me have, somehow, accumulated 6 of them: GN and NP.

I guess being in the hobby for over 60 years 'does that'!

This is an O scale brass #50 UP Turbine that i just received and although I've collected UP brass since the 70's, in all scales, this is the only one in existence in O scale. It was built by two Japanese craftsmen in 2012, for a local Japanese club. The paint, brass sheet relief, brass details and see thru screens is right up there with the best of the OMI Turbines....in fact your would swear it was built by Ajin or Samhongsa. The only give-a-way is the thinkness of the brass sheet used and the under floor drive.

It has "magic carpet" type drives, but built by the model builders and is much more sophisticated and robust. It leaves the interior completely open to add a model of the turbine prime mover,  which I hope to do.

Not to turn this into a PRR thread... but....

It is interesting that for the 2-8-2 electric PRR went with L5, and the 4-6-4 they went with the P5

It seems like they were saving _1 through _4 on each class for iterations of steam classes. After the K4, maybe they figured they only needed 4 tries to arrive at their perfect engine for each wheel arrangement.

All sound good except for the B6 and A5!

The drive is impressive , and follows philosophically the prototypical "electric" (turbine or otherwise) traction motor nestled down on the axles arrangement.

Oddly, the only current traction motor-style "O" model arrangement of which I am aware is on certain moderately-priced Lionel, RMT and former entry-level K-Line diesel equipment, rendering it more "accurate" than the pricier vertical or driveshaft-type can motor architectures.

Beautiful loco.

GN W-1 B-D-D-B electrics.

Imported by Custom Brass models in 1976.

These were equivalent to the Big Boy only the lead and trailing trucks were powered.

These were the largest single engines electrics ever made.

They were 15.5' high and I read where the crew, initially, ducked when they entered their first tunnel.

The GNRY had 2 of these; 5018 and 5019.

The 5018 has a non sound decoder.

I installed a Tsunami electric decoder in the 5019.

I painted this engine back in 2016.

I acquired the 5018 pre-painted by the previous owner.
