Re: NG cars on foreign tracks

Traffic was not transferred. Traffic was loaded in cars based on the destination of the shipment, in order that foreign cars were returned to their owning road. C&S cars ran on D&RG, RGS, and on the logging lines.
DB&W cars have been in Silverton. The Silverton Northern cars have been seen on the RGS and D&RG.

Even more unusual, there were cars in logging service owned by the lumber companies which also operated over the common-carrier lines when in their own log trains. The Safety Appliance Act had exemptions for 8-wheel log cars if the coupler height was less than 25", and locomotives used exclusively for log service were exempt. The Rio Grande & Southwestern moved onto the San Juan Line at Lumberton to reach its interchange yard north of the main line, where it also connected to the Rio Grande & Pagosa Springs. The Pagosa Lumber Company ran over many sections of the Pagosa Springs Branch of the D&RG up until the mid teens, with train that had no air brake cars. The Rio Grande & Pagosa Springs had 10 Cattle cars which ran in interchange over the D&RG. Many of the shipment of coal from Hesperus and Porter on the RGS ran in cars of the C&S lines and predecessors’. A Argentine Central car is photographed at El Vado on the RG&SW, but that might have been a sale relocation. Uintah RR cars did not egress over the D&RG as their air systems were different and their freight was reloaded into standard gauge cars.
