I plan to model a loose representation of the ATSF, the UP, and the SP from
1950 to 1960.
The layout will be centered around well defined interchange yards. Although the ATSF will be the dominant player, the UP and the SP will certainly share some of the spot light. I plan to define specific locations as being serviced by each individual RR, thus necessitating the need for two or three distinct interchange yards to assist the three RR's in their shared delivery effort.
The layout will be completely fictitious, but I do hope to remain fairly accurate with regards to operations and era specific equipment. My modest collection of five, model RR, reference books [by John Armstrong, by Tony Koester, by Andy Sperandeo, and others] have been the primary resource for my track drawings with a LOT of terrific input from this newgroup and a couple of other Yahooo, interest groups.
