I found with many of the new Hornby Gresley coaches, Pullmans, Staniers and Bachmann Mk1's derailments were quite common on my code 75 layout. This didn't happen with my US stock so I decided to get a back to back guage and compare it with my NMRA standards guage. I found the that by adjusting the wheel back to back the same as I would for US stock and the derailments disappeared. I still get the odd one but it's a piece of track I know I've laid badly.

By changing to code 100 i have elinated this problem. If I was starting again I would go code 75 all the way
