Too good not to share. Still photos shot around Avery Idaho in May, 1973, shortly before the MILW was abandoned.
The history on the Little Joe locomotive is kind of interesting. Originally built for export to the USSR on the Lend Lease program of WWII. But the war ended, and Little Joe Stalin started acting stupid, so Congress decided not to send them. The trucks had to be regauged to 4’8" from the Soviet 5 ft gauge. Otherwise, no changes needed to be made. The MILW bought them as war surplus for a song.
