Plymouth No.14 "Chunion Pacific" and a sister locomotive top and tail GEC AMAX locis 3534 and 3533 from the Loci Shop (visible to left of shot) to the tail track, for another empty test run into the mine. Another small diesel locomotive is visible in front of the Loci Shop, either jacked up for repairs, or modified for maintenance use in the 3% grade tunnel. Any further information regarding these diesel locomotives would be appreciated.
