incline gradient

[phil s]

Can really see the camber on the curve on the picture... Does that loco make it up and down ok with four coaches on?

only got 3 coaches at the moment and it goes up there with out loss of any speed, you can see the loco with 3 coaches at the top of the viaduct

forgot to say it must be an optical illussion, i have just measured with a vernier, the bottom curve is the same inside and out, the top curve measures 56.5mm outside & 55.5mm inside, only a differance of 1mm at 55mm wide
will this be ok as this is my first time building anything like this, all advice is taken onboard

thanks phil
