I used to think it had something to do vibrational issues and for structural reasons the tracks had to be ballast, although obviously that's not the case as some sections have been replaced with concrete by now, and the apparent issues along 4 Avenue a few years ago:4 Avenue between 86th and Bay Ridge Ave is or used to be all ballast... Until a church around 77 Street complained about vibrations from the tunnels below causing cracks and structural concerns in 2014. The result? An R32 (R) test train for "vibration testing" along 4 Ave. Shortly after the 77 Street station became entirely concrete with CWR. That R32 (R) in May of 2014 was supposed to ONLY run the night shuttle from 36th to 95th, but either crews refused to pull it out during the night or the vibrational testing was assigned during the day and the result was two full round trips from 95th to Continental despite being laid up all night between 86th and 95th signed as 36 Street - 95 Street "Shuttle". I still remember going down to 95th to check up on it after hours of it sitting there and witnessing the signs being scrolled to "71-Continental" going ohhh shittt... Very interesting times indeed. |
