I did some work on these beasts over the past week. I mounted up some Kadees and reworked the controls. These were originally PS1 when I got them back in 2006-7 and were soon converted to EOB with components to control the smoke units along with the lighting and coupler in the rear A unit. I changed out the EOB for ERR cruise and added sound to the rear A as part of my unboxing efforts for this layout. I swapped out the cab crew with some Scenic Express figures.
