Attaching track to foamboard?

[RobertInOntario]

what kind of track are you using, sectional or flex? For sectional track, I would second he latex caulk. For flextrack, I would want something that sets faster - or perhaps stick with double sided tape. You also may want to look at some of the track that has the roadbed attached.

Good question. For most of the layout, I"m using sectional track except for one difficult curve (approx. 17.5"R) where I resorted to using some Atlas flex track. It's actually the flex track section that I'm most concerned about. So far, the pins/spikes are doing a good job holding it in place but not sure for how long.

Thanks,
Rob
