I don't know, but I seriously doubt that. Early in the 20th century, rollers were used in huge quantities on gas powered touring autos, not super heavy railstock. As for the arnines, the city was in no mood for expensive experimenting with its new subway cars, and wanted to go with tried and true mech-tech to establish themselves. There was an awful lot of stupid politics, fear, and penny pinching at work then.Maybe the BMT's Zephyr had roller, ie: frictionless bearings, I couldn't notice any JB lids on any of the photos I've seen. The BMT's "oddcars" seems the best candidates for pre war NYC based subway cars, with rollers, if any existed. |
