ORIGINAL POST:
Another morning rush hour with the potential for crowded MARC trains. The following trains are going to run one car short, which means they might be more crowded today: Four Penn Line trains: 503 (departing Perryville at 4:40 a.m.), 402 (departing Washington at 6:45 a.m.), 411 (departing Baltimore at 7 a.m.) and 415 (departing Baltimore at 7:40 a.m.). And Brunswick Line train 876 (departing Brunswick at 6:33 a.m.).
