LEHIGH was cut up a number of years ago, the tug in the video is HAZLETON, both her pilothouse and stack were shortened for use in shipdocking service. The portlights in the lower level of the pilothouse that used to be normal viewing height were almost on the deck after the shortening. If BETHLEHEM has been disposed of, it got by me, would appreciate the details if you have them. Last thing I knew she was with Turecamo prior to their being absorbed by Moran. My recollection is that she had been re-engined along the way, that was likely to keep her going as Moran has disposed of all their other Cleveland Diesel tugs.
By the way, I showed the DIESEL RAILROAD TUGS program to the Tugboat Enthusiasts in Portland, Maine last year, but there has been very little interest in that program among railroad enthusiast groups and I get the impression that railroad marine operations are starting to slip away into the distant mists of ancient history.
In the YouTube clip, you can see HAZLETON hits the bottom in about 90 feet of water, the bow stops abruptly for a couple seconds before it disappears beneath the surface. Looks like she probably landed upright. She has company out there, the Erie Railroad's PATERSON was scuttled in a similar manner.
