At least that the way I heard it.
Well, sort of correct. The term "Consist" can be used in many ways throughout the railroad industry:
1) The most common use is for the motive power make-up, i.e "Your power consist is three 'big ones' on the head end and a single DPU on the real of your train".
2) Your train consist is 63 loads on the headend, and 23 empties on the rear.
3) Your "light power move" is a consist of 12 units, all MU'ed, but the rear 10 units are isolated, i.e. the power plants are "off the line".
