Re: The RFW Served a Purpose

I rode the R160 "RFW" just the other day on the F from Roosevelt Av to Lex/63 to check out the CBTC signaling, after not having done that for several years. What a change! It's remarkable how many signals they've removed.

After the leaving signal at Roosevelt Av (a home signal, top head blinking green, bottom head dark), the next signal isn't until deep into the tunnel under Northern Blvd (the street, not the station). Then there are a few more around where the old timers used to be, and then some approaching the 36 St interlocking. At the end of the 21 St platform there's a small yellow sign saying that CBTC ends there.

Of course ATO is not yet in effect, so the train operators are really operating. Ours slowed down in the same places where the timers used to force them to. How do they know to do that now without wayside signals? Do they get some indications on their computer screens? Do they have to take their eyes away from the road often to look at the screen? That sound dangerous to me.
