Yes, this title has a point.

I'm writing a series of short stories about my own railroad, which has some of my own designs. One of them is what I call the A+BC45s. It has the layout of a basic model six axle diesel (SD70, Evolution, etc.). However, only the rear axle is a C truck. The lead truck is articulated instead. To give a more visual description (because I suck at drawing trucks as a whole), it's like the B+B trucks used on the GE U50s and ALCO C855s, but instead of two axles leading the truck, it would be one instead. Sort of like this:

o+oo-----ooo instead of ooo----ooo

This give the loco an A+B-C wheel arrangement, as it's intended for running high speed freight trains. High speed meaning over 70 miles per hour since that's what all freight diesels seem to be geared for these days. I wanted to keep the six axle layout with each axle powered, but make the front end more flexible than a C truck so that there wouldn't be a repeat of Amtrak's early failures that were the SDP40Fs, P30CHs, and E60s.

Here's my question to you. Do you think this idea would work, or would it just be easier to make the first axle unpowered like with the Baldwin Centipedes' first and last two axles?
