I Was Looking at this Link ALCO MLW BBD Data Sheet Index · MagnumMacKivler/RLCPT2 Wiki · GitHub the other day I was curious as how The UNBUILT ALCO Century Series would fall if built . Here is where I would List them. Note how wikipedia ALCO Century Series locomotives - Wikipedia Lists where production models and Non Production models are --where Non Production models are listed.

As for the ALCO C860 try here >C860 · MagnumMacKivler/RLCPT2 Wiki · GitHub states the following on the C860... Designed as a follow-up to the [COLOR=var(--color-accent-fg)]C855[/COLOR], the C860 would be a [COLOR=var(--color-accent-fg)]C855[/COLOR] with [COLOR=var(--color-accent-fg)]C630[/COLOR] carbody features and a corresponding increase in power.
