The train I saw today was nothing special. It was just dash-9 widecabs for power (NS’s most common road power–they have over 1000 of these units) leading NS 290. However, it was a beautiful day to be outside for a bit at lunchtime, especially after the long hot and humid spell we’ve been having.
Photos and video below. The video has a little bit of horn echo as 290 blows for the private crossing.
