Most of the more common, modern GE and EMD locomotives that were around then are still around, but what was rare then is even rarer if not gone completely.
In this one we hear a lot of the WCH mechanical bell that lasted until 2014 at Green Rd., with its distinctive slowdown in ringing as the gates rise. The bell was visible in several scenes in the original footage, but was cropped off in the conversion to widescreen.
Call me crazy, but I could have sworn the Maple Ave. crossing on the UP Adams Sub in Sussex was on the site, but it would appear that it's not. I have a full photo set of this crossing from this era (actually taken the same day the clip that begins the second video was recorded)...but apparently I never submitted it to anyone here. Must have just imagined doing it.
Looks like the crossing still has the same basic signals, but the bell has been replaced with a GS or NEG (not sure how to visually tell the difference) and of course the newer standard straight-striped gates and blue tags added.
