[quote]QUOTE: Originally posted by daveklepper It is in the Winter 2004 issue of CLASSIC TRAINS, and you are right, the first and second trucks are powered. However, note that both on this early example, and the later fleet of articulated BMT subway cars, if not the D Tyoes, then certainly the Multis, the Budd "Zephyr", the St. Louis Bluebird, and the Pullman aluminum Green Hornet, many articulation joints had trucks with motors underneath. Also the North Shore's Electroliner. But there was essentially just zero difference between the trucks under the articulation joints and the trucks under the rigid car body bolsters. What was different was that each of the facing units had ring, on above the other, that fitted the fat steel lubricated pin that projected down to the centerhole of the truck bolster. If this kind of design could be made strong enough, there is no reason it could not be applied to freight locomotives and there should not be any loss of adhesion. [/quote] It is probably a moot point since the whole "bigger is better" diesel craze has become passe, but I had wondered why someone hadn't tried to creat a two engined articulated locomotive rather than the twin engined rigid framed behemoths we ended up with.
