Double Dual-Mode.
NJ Transit ALP-45DP no. 4508 (Bombardier, 2010-2012) and ALP-45A no. 4539 (Bombardier, 2019-present) are on the west end of their respective trains seen passing at Harrison Station. Notably one is operating on electric power and the other on diesel power, which helps to identify one as a North Jersey Coast Line train (Train 3511) and the other as a Raritan Valley Line train (Train 5444), the latter of which is headed to the Meadows Maintenance Complex.
