I was going to post this on another thread, but I couldn't find one that was appropriate;

From the 1960s into 1980, the Long Island Rail Road had an additional bus system called the "Road & Rail" buses designed to take commuters to train stations from places where the railroad didn't go, or from when lines were being rebuilt, or threatened with abandonment.

Quite a few GMC "New Look" buses here. Snookie, you should be especially interested in this.
