At M E Shows, a 7 1/4" gauge model is shown, as manufacture progresses.
It is going to be quite a beast when completed.
Even transporting to a venue will require a hefty vehicle. An the curves of the track cannot be too sharp, given the wheelbase o the eight coupled wheels.
The prototypes did not see too many curves, hauling freight trains, long distances across U S A.
When the original was s described as "The largest locomotive on earth" he was unaware that it had just derailed, and was on the earth!
