I have been continuing my examination of harbor terminal layout design, I find R1 design translates well at 75% reduction to HO 18"R, I took the plan above for a fellow on MLS and reduced it to HO, which I am now so very tempted to try:
This also includes another harbor terminal layout, the first large terminal in the first pic above with the circular freight house was based on a terminal in the Bronx, this lower one is based on a Harlem area terminal, again totally self contained little railroads with lots of operations. The upper right layout is a condensed version of the Harlem yard, both are based on plans from Carl Arendts website.
My biggest problem is that I have far more ideas than I have space to provide for them, so almost all of them will never get beyond the plan stage
