How's this for an interesting looking beast? This is the shell of a B30-7 that is now a "Control Cab Remote Control Locomotive" or CCRCL. Basically, Union Pacific removed the prime mover and the fuel tank (note that the exhaust stack is capped). They also removed the control stand and blacked out most the windows on the cab. They also installed remote control electronics to the units. The unit can still be MU'd to other units, allowing this unit to act as a "bridge". This unit can be hooked up to a powered unit and the person on the ground can then remotely control anything.
