Has anyone modified their postwar Lionel S2 turbine engine into a 4-8-4 ?

Why would you want to replace the 6 wheel trucks with 4 wheel trucks? I think you can get them from Jeff Kane.

The 671-93 front truck for 671,681,682, & 2020 is just $10 at The Train Tender.  The mounting, and truck, are unique to the turbines.

Why not? Isn't imagineering permitted? It's not exactly a scale loco to start with. 4-wheel trucks might look better IMO !

 

I think it might be "interesting" as a 4-8-6 or 6-8-4 or possibly a 4-8-4. The 6-wheel trucks are kind of silly looking because the wheels are so crowded and the center wheels don't have flanges. They have about the same wheelbase as a 4-wheel truck. Those 6-wheel trucks might look better under the tender!

 

It's not my loco, and my friend probably wants it original. But this will be his third turbine engine and if he gets it rebuilt, I may try to talk him into selling it to me. Maybe I'll have the only 4-8-4 turbine engine, thanks to special engineering to keep the axle loading within parameters.

 

 

Rob, Thanks for the info, I will pass it on to my friend.

If the front truck is missing the 671-185 pivot screw is probably needed also.

If you want to be prototypicly different then go with a 4-8-4 arrangement since its origonal design was of that arrangement.....

That's kinda what I was thinking. I've changed the post title to ask if anyone has improvised a 4-8-4 turbine with postwar Lionel parts and been happy with the appearance.

The Pennsylvania Railroad's class S2 was a steam turbine locomotive ... The locomotive was to be a 4-8-4, but wartime restrictions on light steel alloys increased weight until six-wheel leading and trailing trucks were needed.

My train repair friend Ed restored this 671 "parts loco" to operating condition. Bought it for $40 at a train show. Until we get the original replacement parts, it's an 0-8-6 heavy switcher. (If it was mine, I might have tried making it into a 6-8-4 just for kicks).

 

Ed has a couple complete 2020 turbine locos and I see that the front and rear 6-wheel trucks look the same except for mounting details.
