Will the bigger Pre-War Lionel articulated Passenger Trains such as The Hiawatha , The Rail-Chief, etc go around tubular O-31 curves & switches ?
Track Dept. needs to know PDQ.
Haha. Thanks.

If not, what about O-42 or O-54 ?
No, the large streamliners were made for 072 and will not run on anything smaller. Sorry.
RSG,
artyoung is absolutely correct the originals were made to run on 072/711 Switches and curves, nothing less, although some will work with the 054 defending on the trucks that were used on the rolling stock.

If the cars will run on uniform O-54 (say a full circle, no straight pieces), but not on an O-54 oval, that would indicate that the problem may lie in the lateral offset of the ends of two adjacent cars at the point of leaving straight track for the curve. If that is the case, using one section (14-3/8 inches) of O-72 as a transition should materially reduce the problem.
If the cars are articulated over a single truck, and 2 or 3 units together will not bend to the radius of an O-54 circle, then of course an O-54 oval cannot be used.
Otherwise, if the transition idea is found workable, it will add only 5/8 inch of width to each side of the oval, which adds 1-1/4 inch width to the table holding the track.
