Here's the full note from MARC:
Attention Penn Line Passengers--
Due to a continued shortage of equipment, the following trains will once again be operating with one less car than normal:
This afternoon (Sept. 2)--Train 436, the 5:34pm departure from Union Station
Tomorrow morning (Sept. 3)--Train 513, the 6:30am departure from Perryville / 7:15am departure from Baltimore Penn.
We realize that this is the third straight day of this service disruption and that it causes inconvenience for our passengers. We are working with Amtrak to get more of our electric locomotives back into service which will allow us to return the seventh car to this consist.
We appreciate your understanding and patronage.
