You know, that black stuff used for tunnels... Cost is roughly $130 for 20' of this stuff. Well my questions are...
How do you install access hatches to reach your trains?
My 1st tunnel is a slightly curved 20 footer.
How many and how far apart do they need to be?
Is there anything else that will work as effectively as this stuff?
thanks
