01400's on Red Line work trains

Postby CSX Conductor » Fri Mar 18, 2005 11:17 pm

Anybody know why they MBTA uses 4 1400's on work train consist and then uses a normal 1500/1600/1700 series of 4 to 6 cars in the consist of the second work train? Why can't they use 2 1400's on each work train? Just curios.

As you probably know, the 1400's, most other red line trains, 1200's and 600's are all married pairs. They share certain components. As a result, when an air problem developes it usually affects both in the pair. While each car takes it's 600v independently, the control voltages (37v) are likely to affect the pair as well.

If one of the dueces break down, the other(s) will pick up the slack and move the train off the main line. A single duece, breaking down, would require a rescue train (tack-on in T lingo.)

a 2 car 1400 work train may not have the power to push the work flat up a grade, and may get stuck on the line

Yes a 2 car 1400 is enough to pull a disables 6 car train of 15/16/17 or 18s . But Robert is right if the train goes bad they just split it in two and push or pull the disabled cars. Thats why the T no longer runs 2 car trains at nights or Sundays anymore. They can move the train quicker if it becomes disabled and not have to wait for its follower, which might be 10/15 minutes behind. Rember those days of 2 car service trains on Sundays or at night. AH MEMORIES :P
Farewell old friend thanks for the memories.

I remember those as well, even on Saturdays they did it too, but that all ended in, yup, you guessed it, October/November 1986, when the 015/1600s were at PX/JS for rehabilitation and when the 01700s were being accepted and thus the 4-car minimun rule came into place just in time for what would eventually be 1986-87, the big year of transition for the Red and Orange Line altogether.
