K-Line F40PH...2 Rail???

Looks like an MTH with 3-2 trucks. The rollers just unscrew from the bottom of the truck, and it looks like 3R wheels without the rollers installed. 

K-Line did not make 2- rail locomotives.  They were easy to 2-rail, since NWSL made a kit.  Going back to 3-rail would be problematic, unless the original wheels are still with the locomotive.  I typically pitched mine in the trash.  I now know that 3-rail wheels and trucks bring a premium on eBay.

 

Wait for a 3-rail version.  Cheaper than re- converting.

Here you go - all K- Line, and all 2-railed.

 

The f40 in the pictures above is an MTH. The trucks have a molded in snobber( shock absorber) detail that was not on the K line models. Also if the side fan grills look like wire mesh, that is another mth trait giveaway.

The 3/2 trucks have plastic bottoms that are removable. There are also the flat metal traces that carry the current between wheels on the powered models.

 Those look to me like the fixed MTH trucks with trapped axles. Not a big difference unless you need to swap out the axles.

Thanks for your replies. bob2 do you think or know that it has 2 rail wheels, and I'm just a train around the Christmas tree guy. I didn't know there was a difference in wheels between 2/3 rail.  I picked up a MTH Bombardier Tri-Rail 2 pack (I'm a sucker for double deckers) for $80 shipped.  I thought, let's keep the theme up.  Last years I bought a MTH E8 ABA CNW set and a 4 car bi-level gallery car set. I never ran it due to being gone most of the Holiday season, but I finally put it on powered track.  I had the power on only a little on a conventional transformer.  The lights were blinking, the strobe was strobbing, the engine sound rumbling, the bell was ringing, and then there was the horn sound.  It did 3 beeps and the stuck on constant.  I decided to hit the horn button, which did make it stop.  3 seconds later the horn went off twice and then an arc/bark/snap/puff of smoke!  It never moved.  I have it in for repairs, but haven't heard anything yet. At least I didn't melt the shell, and I didn't bother to remove the shell to see the damage.  I'm not a rivet counter, but have taken a liking to being as realistic as my wallet allows. bob2, you also got me with the FM Trainmaster.  I have a Lionel Reading and a Williams Reading and run Williams heavyweights.  CNW did not has the big one, but they had the baby, and I do not know if they ever pulled the bi-levels.  My friends Dad was a conductor for CNW on the Ashland branch. He worked on the Flambeau 400. When I was a kid growing up in Chicago, I never thought that the bi-levels(double deckers) were used outside of commuter service. My house as a kid was across from the Rock Island 91st Street station.  I would hop on and ride to 95th street a few nights a week. Now...I would almost take out a second mortgage to get a Rock Island AB6 and some good corrugate bi-levels!

 

I can't find an 809 F40PH in any MTH catalog.

Nice paint.The locomotive looks like a standard 3-rail MTH with the rollers removed (or it could be a non-powered unit). The wheels are hi-rail. It's hard to tell if it's Premier or Rail King as a lot of Premier tooling went into Rail King offerings. I don't recall MTH offering a Tri-Rail F40PH but it seems plausible if they had the Bombardier cars.
