Install Woodland scenics O gauge roll of track bedding for curved sections of track?

I don't know about the WS foam roadbed. I bought a similar product from a supplier on eBay. I slice a section in half and then cut kerfs (about every 1.5") on the outer curve of both.

The Woodland Scenics track bed that I've used is cut down the middle and bevelled ... just like cork.  It won't break when curved as it is flexible foam-type product. On 027/031 curves you might have to notch the product for curves.

I glued mine down just like you would cork; the WS roadbed is made to be split in halves-that way going around corners does not stretch the outside edge and compress the inside edge too much. Just glue the halves down and hold with stick pins until the glue sets. Never had any issues with it afterwards.

I cut little triangles out of mine to bend it on tight curves when I used it.

Ditto, works great.

On curves I cut mine down the middle to bend and cut manageable sections off the roll (24” sections)  I didn’t use glue but had Foam pins I would use to hold in place adjust as needed.  I use Atlas track so then would screw down track and use a few more screws to hold foam in key spots before removing foam pins.  So on a curve I would slide in the next section to be flush with the last section pin down and continue to shift and pin as I installed then screw down Track then road bed

I’ve moved some track after so using screws was easy to move foam bed to new location or when I shifted foam bed to obtain a equal spacing

Thanks for all of this great info.
