Actually, having the yard leads N/O 207 St station instead of where they are now would be more efficient since there would certainly be sufficient room between the station and the yard for yard moves to be made without interfering with the road. One of the most efficient terminals on the system is N/Lts since it has 2 single Xovers instead of a diamond so that a switch failure on one switch would probably not affect the other. With the yard past the station, trains can be put in and laid up directly from the station without having to go somewhere along the mainline like at 207 St to change ends and access the yard. I noticed over the years that on my civil service promotion tests to both the T/D and Trainmaster titles, the essay question involving an incident on a fictitious line shows a terminal area that bears a very strong resemblance to the N/Lts terminal and yard leads. |
