Not with a bridge. A trestle or viaduct might be OK. There is a good Kalmbach book: "Model Railroad Bridges and Trestles". Visit

-------------------------------------------------- "Model Railroad Bridges and Trestles":

Certainly trestles or viaducts are considered types of bridges.

Only in a broad, all-encompassing sort of way. I was *trying* to be more specific without resorting to a statement like:

"Not a deck girder, beam, through girder, deck truss, though truss, suspension, arch, continuous truss, or cantilever bridge."

(I *think* that is the complete list of what *I* mean by a 'bridge', excepting trestles and viaducts.)

Generally *I* don't think of trestles or viaducts as being 'bridges' except in a rather broad sense of the term.

Note: even trestles or viaducts are almost never built as a continuous curve

-- they are built as many *short* straight spans connected at slight angles. Trestles or viaducts generally have far shorter 'spans' than a bridge normally would have.
