just these Iron Highway piggybacks in their still-experimental stage (note the HX prefix to the power-unit numbers). they made'em a little longer toward the end of the experiment, then scrapped the technology (undercarriage lasers would get too dirty & malfunction is what i eventually heard) & replaced it with the Xpressway piggyback service, making the consists much longer.
I remember seeing proposals for these in both the RR Trade and Railfan press in the 90s. If I recall correctly the original drawings showed integral power units at each end that looked like contemporary GE passenger locomotives.
CP's annual report called those blue contraptions a "radical new technology" but i've been able find out nothing about what kind of power those things actually are. any idea?
Trains were super short back in 97?

I wonder how well those sets took crossovers at 30 or 45 miles per hour.
