Re: Flex Track for a curve in pvc pipe or what would you reccomend?

The windows are above ground and we would probably have to do something like that but..., will the grade be to steep that when trying to go up the locomotives will not be able to with a load?

The grade up a helix depends on two things - the radius (diameter) of the helix, and the track-to-track separation. A helix radius of 36 inches and a separation of 4 inches yields a grade of about 1-3/4%. Up such a grade, a locomotive will haul about 30-40%% of the load it can haul on the level.

The number of tunrs in the helix is of course the toal height to be overcome divided by the track-to-track separation.

To answer that we need figures, as Wolf said. If you are above ground why do you want to use a pipe?

Straight. Otherwise -- derailments would be suicidal.

Maybe straight PVC sections with a few "clean out" boxes that can be opened up to hold the curved parts?
