I have the Birth of California Narrow Gauge book by Bruce McGregor and I am pretty sure it has drawings of the Carter Bros trucks. However, they are narrow gauge not std. Cliff might know a better source.Does anyone have drawings or a source for drawings of the CPRR arch bar swing-motion California style trucks? These were used on V&T combination box cars in the 1870's
A more modern version can be found on Brill trolleys and the East Broad Top M-1, which has trolley trucks by Westinghouse. I figured out how they worked by trying to produce drawings. The "swing motion" is quite pronounced on the EBT track.Swing motion trucks are very multi-layered, lots of moving parts.
