Yes, this is a common problem on LGB switches - I am able to route my live steamers through the straight leg of the switch and avoid the problem!
It is a question of both the gauge being wider than 45mm through the curved part of the switch and the sharp lead in angle to the check rail, I would go with changing the check rail inthe long term but also have a look at this page, usefull tip on correcting the gauge and other bits.

Hope that helps, Allan.
