US Signaling (Caltrain): Freight Speed Signaling | Mileage, Station and Speed Signs (TSW tutorial)
In a second go for the speed signaling system used by Caltrain in the San Francisco bay area, we are looking at the different speed regimes for passenger and freight trains and this time also the aspects on dwarf signals, including the special ones in the San Francisco station area.
Full "Ballasting Act" scenario on the EMD MP15DC switcher locomotive in Dovetail Games' sunny Peninsula Corridor DLC, running gravel gondolas from South San Franciso to almost the Caltrain CEMOF (Centralized Equipment Maintenance and Operations Facility) at San Jose, featuring short tutorials about the Caltrain wayside speed signaling signals (43:10), the dwarf signals used in the speed signaling system (57:46), signal progressions (1:07:45) as well as mileage (1:17:53), station (1:21:27) and line speed signs (1:23:40).
