It's summertime and that means MARC Penn Line equipment is crapping out and people are getting stuck on trains.
This happens EVERY year on the Penn Line. And there's a pretty simple culprit:
MARC bought the wrong type of locomotives for the climate.
To my knowledge, nowhere else on earth are the HHP-8s exposed to high humidity and high temperatures like they are here.
If you have to work in DC and take MARC, all I can suggest is to take the Camden Line in during the summer.
