The Burro Motorized Crane Unit No. 3360 must have caused some Lionel design engineer some sleepless nights. Not only would this unit move itself along the track, but it used a clever clutch system to swivel around while it was moving and track trips to reverse direction. The lever on the side of the unit that reverses the unit can be operated by hand or by use of these track trips. Only one track trip came with the original unit.

Lionel offered additional track trips through their service stations (Part No. 3360-125). This unit was available for two years beginning in 1956, and came with solid non-operating couplers.

Included with this unit was a Parts Envelope No. 3360-94 that contained the track trip, a tube of lubricant, and the instruction sheet No. 3360-91 dated 8-56. The discoloration of the envelope that is pictured to the right is caused by leakage of the lubricant.

We’ve picture three pages of this instruction sheet below that used DARK BLUE ink on LIGHT BLUE paper. There are no variations.
