I finally ran my first night time run on the Morristown line with the Arrow III. I noticed that the light outside of the train to designate if the doors are closed and train is ready to move doesn’t light up on any of the cars (I believe it’s green when ready to move, yellow when doors are open). It shows on the Multilevel Cars, the Amfleet Cars, and the LIRR/MTA cars. So wasn’t sure if this was a bug or the light just wasn’t added in for them.
Looks like this has already been fixed in the most recent patch so was a bug that was already captured. Thanks!
