Re: Park Avenue (Brooklyn)

If you notice in the photo, the route “request” punch which basically only lined up the automatic tower for whichever train was ready is on the M/Ms side on M1 tk. Sometime before I started in 1966, the route request box was moved to the platform side. Most likely it was done in the 1950s when the Qs replaced the BUs. For some reason, when both pockets were empty, the automatic interlocking lined trains up straight iron into M2 tk and only lined them into M1 when M2 was occupied. I would have though that it made more sense to have the arriving trains cross over and leave straight iron, but for whatever reason it wasn’t done that way.
