I was in the Union Turnpike station yesterday morning to catch the 
to Brooklyn, and I noticed something odd. On the Jamaica-bound express track, there were 2 R-160's parked back-to-back, as is usual when they are storing trains down there or blocking off the express track or whatever.
The odd part was that 1 of the trains had all of its doors open to the track side (not the platform side), but all the interior lights were off and the sign said "Last Stop". The train in front of it kept making all sorts of noises, especially air hissing, like when a train goes BIE. The interior lights kept flickering on and off throughout the whole train. There was nobody in the T/O or C/R positions, and no MTA employees in sight.
The scene just didn't seem right, so I went to the S/A to tell him something might be wrong, and then caught my train. I'm not sure if anything happened after that.
Anyone ever see something like this?
