At the FREMO meeting in Übach-Palenberg Diamond Valley had it's first test. The concept of the town with the industries worked very well. But I did run into some problems with the turnouts.
There were problems at the frog. The two rails at the frog toe
are too close. The wheel (of tender trucks at steam engines especially) run
on one rail - but the flange touches the other rail. With DCC the booster
My fast solution was with a file. But for a fool proof long time answer I will replace the frogs. With PROTO:87 frogs there're no dead spots. That's for small critters important.
