Modeling Baldwin Road Switcher S/G stacks?

[Deleted]

Could someone describe the best way to model the Baldwin Road Switcher steam
generator stacks (as found on AS-16s, RS-12s,etc)? It appears there were 2 types. The SAL had an exhaust
roughly 9x18x12" What about the intake?

The PRR (and PRSL, RDG) had tubular stacks?

What is the best way to represent these in HO?

Thanks in adavnce!

Can you post a link to some photos? I do better when I see what you are asking help for.
