@Richie C. posted:I think they are pretty equal in terms of providing adequate support, with a slight edge to the foam risers.
Part of the answer depends on the 'look" you are going after. The trestles have a more nostalgic look, while the risers can be scenically covered with foam, plaster, etc. and ground cover to look like one long hill that the train is traversing.
OTOH, the space between trestle supports can also be used to place scene "vignettes". For instance, I have a log cabin in between two trestles in one location and a hobo campground in another and this fishing scene in another.
Great work on the scene! This pic really brings out your point of having the trestle provide more opportunity for creativity.
