My Thoughts on Gondolas
I don't like any of the gondolas that are currently in the set. (Yes, I know, we aren't going to change them before the first release...) I don't mean the coil cars, those are fine. But none of the cars listed as "gondolas" look realistic. Here's what I'd like to see:
Gondola carrying goods:
You can see it's full of various-shaped crates. We don't need the hobo though.
Gondola carrying steel:
Notice it's stacked full of steel beams. Sheet steel is never shipped in flat sheets like plywood (like we have in the current gondolas), it's always sent in coils (which we have in our coil car.) A gondola would be used to carry I-beams, tubular steel, or pipes. I'd say we should have all three, as random appearances, very similar to what is in the DBXL set but with American-appearing gondola cars.
Gondolas don't carry grain and never did. Before the modern hopper car, grain went in boxcars. Likewise, fruit doesn't go in a gondola, it goes in a reefer; and food goes in a reefer, a boxcar, or a hopper (flour).
So I think our gondola needs only two refittable cargoes: goods (in crates), and steel (beams, pipes, as described).
We already have a woodchip gondola/hopper, which appears in with the log cars, as it ought.
