Very nice looking motive power - well done. Love the track plan and how you've been able to fit a LOT of operation into a relatively small space.
Have a couple of comments. First is about the staging ladder track at Stockton - using one LH and 4 RH turnouts rather than 5 LH's would allow for a straighter approach when drilling. As designed now, there are a series of S curves trains will have to roll thru.
Secondly, how do you plan to throw turnouts - manual or remote? That first ladder LH turnout in staging (closest to the corner workbench) seems to be a bit of a stretch if you have to reach back there.
Please keep posting on your progress - especially building the 2-6-2.
