Speed Restriction Between Metro Center and Chinatown

Postby Chris Brown » Mon Dec 19, 2016 5:04 pm

I really want to know what is happening on the Red line between Metro Center and Chinatown going in the direction of Glenmont. It seems like every single time I ride the Red line going towards Glenmont, the train will slow down and do that annoying "gas brake gas brake" thing between Metro Center and Chinatown. This has been going on for what seems like a year now. It happens both at rush hour and off hours.

What is the issue and what is causing it to last so long?

Throttle application followed by a brake application followed by another throttle application and another brake application.

Sounds to me like a combination of bad track (reason for slowing upon approach) and repeated momentary loss of cab signals.

I've not noticed anything out of the ordinary. Not any more than normal poor operator handling of the controls that goes on everywhere else in the system.

Bobbing track circuit between Metro Center towards Gallery Place. It's not the operators' fault (this time, at least).

For an entire year? That is one of the shortest distances between stations on the system. Why is it taking so long to fix?

Good grief. You'd think that would the easiest and most obvious track circuit to fix. Plus, didn't they just rehab the track circuits on the red line recently?

Politics and contracting, as far as I'm aware. Metro says it's their fault, they say it's Metro's fault. ¯\_(ツ)_/¯

This is not unheard of. There's stretches of MTA Maryland's Light Rail that ATP signals tend to fade out at various times, due to how they designed the system.
I ride the (MTA Maryland) Penn Line (between Odenton and Baltimore). I used to work for MTA Maryland's IT department, and out of professional courtesy my responses may be limited. Wikimapia is wonderful (for track/interlocking locations)!
