Oh really, well we did the same for car 57, this was the least stressful way (for the carbody) of moving this kind of old equipment. the trailer frame which is custom built with a pre-stressed I beam on one side to try to remove the age old twist in the CA has its wheels removed to get it as low as possible, then the body is gradually lifted until the Aluminium I beams can be inserted the lift continues until the I beamds clear the trailer sides then two more beams are bolted on across the trailer, lifting a further 6 inches allows the 4 roller assemblies to slide under the caboose frame, then winches get bolted to the I beams and cables attached and the body can be winched across, using wedges of course to prevent it running away.
Its a great system and is stress free for the car and everyone really !
