Posted by randyo on Tue Nov 17 14:31:22 2009, in response to Re: Obama administration proposing federal oversight of subways and light rail, posted by Jackson Park B Train on Mon Nov 16 14:22:21 2009. You bring up an interesting point but in the pre Amtrak/local commuter RRs each railroad had its own signaling system so there is really no difference between what goes on now and what went on before. Each local rapid transit system also has its own unique signal system although there are some similarities between some transit systems throughout the country. Even within the NYCTS, there were 2 different types of signal displays on the 3 divisions. IRT used a system more in keeping with mainline RR signals whereas the BMT developed its own signal system which was later adopted by the IND and is now becoming standard on the entire NYCTS. Despite that even while the old IRT signal system was predominant throughout the division, M/M were able to pick between the IRT and the combined BMT/IND Division and had to deal with the 2 types of signal displays. In fact even within the IRT Division, M/M had to deal with both the old and new signals often on different parts of the same line. |
