A question for our New England "Knowledgables":

In addition to PD3000s and older PS-2s, what other types of covered hopper could be seen in talc service in Vermont during the late 1970s/early 1980s? 

I've come across many photos, especially of Green Mountain Railway Alcos pulling covered hoppers, but the reporting marks are tough to read.

Thanks for any information you can direct me to!
