I want to rebuild my layout to 1970s plus using diesel and electric locos. However trying to find code 100 track (00 gauge) with concrete sleepers, which I need for some of my older stock to run as heritage trains is near impossible. I know Peco have now introduced code 100 flexitrack with concrete sleepers but what about points (not blooming turnouts!!) and standard type track , 3rd and 4th radius curves etc. This query also applies to station kits and some buildings, although Metcalfe does produce some modern type kits. I and I assume like many others we don’t want to live forever in the steam era nice as it was. Anybody help.
