There are six trucks being built new from the ground up by the Friends for three different cars. One set is for the RPO car that was restored in Chama. Another set is going under the 470 car being restored by the Friends in Colorado Springs. (This car is due to come down to Antonito next spring to sit on it's new trucks). The third set of trucks was made to go under the Rotary Snowplow service/cook car (053?). All three pairs are of different construction. Hopefully Ian Kelly will chime in here with more information because he was heavily involved with assembling all of the trucks.
