AFAIK, both "sidewinder" bulldozers are assigned to the East Deerfield wreck outfit,
with just the 200 ton crane kept at Waterville. Depending on the situation, the
dozers are much more efficent in clearing derailments, being much more versatile
and manuverable than the cranes.
PAR is one of a few railroads still operating their own wreck trains, as most
railroads use derailment cleanup companies, such as Hulcher, R.J. Corman,
and others.
