I'm fascinated by the announcement of Scott's latest offering, a unique rendition of an electric locomotive that ran as a three unit combination for a total of 7,000 hp. All three units in the 3rd Rail units will be powered.
I wonder how many of you run a combination of three powered units, and if so why? I find single modern locomotives with traction tires easily pull eight or so passenger coaches or perhaps 20 freight cars. I have a big layout, the outer loop has 120 curves, so can run big trains. I've not seen the need to MU locomotives.
What am I missing? LOL
