Big bridge, little train. CSX W003 (8761 SD60M leading) passed under the Bear Mountain Bridge over Popolopen Creek on the morning of 7/20/2017. While the engine itself is a catch, as it is normally assigned to east of Hudson service, the geometry train is an even more prized target for railfans. Since the end of the Ringling Brothers Circus Train, this is one of the few 'passenger' carrying trains one will see on the River Sub.
