Thank you Giz,
one day, i made a very expensive decission: i put all my LGB R3´s out of order and changed ALL to a VERY fine system of switches.
I have different diameters, the switch in the first seconds has an R3 (1175mm( on the inner track and 1750mm on the outer. Later on we pass the crossing where a junction (snowy) is following with straight switches , the curved track has R 3000mm (arround 10 feet).
having passed the bridges, we enter the pass-station where the first switch is a curved R2000/R3000 switch.
As told, it wasnt really cheap, but i dont regret anything. No more derailments, even when pushing a 12 cars-train the 4% incline. One loco in front, one at the back: NO problem with switches.
Take a look at my homepage, tere is a "pictures"-section with (snowfree) pics of my private layout.
Greetings
Frank
