Hello ltsme here

The plant mounted on the new switch and crossing layout are called PEM's. They are basically lifting gantrys. They will be placed along the layout to lift and slew it over to the single line.
The layout will then be lifted. More plant called LEM's will be placed on the single line and positioned under the layout. The layout will then be lowered onto the LEM's  and transported to it's final location.
There will probably be 16 PEM's and 16 LEM's in total. They are all remotely operated by 2 controllers (1 on PEM's and 1 on LEM's)
