UPDATE on the TimeSaver stencil - according to some B&O aficionados on the STMFC newsgroup, the (T) stencil meant the cars were certified to be used in TimeSaver service, not that they were being used in TimeSaver service. There were many more cars certified (as being suitable for LCL or clean-lading loads) that what actually were used. So it is prototypical for a (T) stenciled Wagontop to be off-road.
