I have some GRS bespoke track for sale. A crossover with threeway point, and extra straight sections, as you can see from the photo. (and previous article in G3 soc newsletter)
Overall length 2.15m, the tracks are set 160mm between rail centres.
The radii are 8' 0" .
The sleepers are creosoted, the rail sides painted with railmatch sleeper grime.
The whole thing is insulated for 2-rail electric operation.
Price £350 ONO plus delivery. (or collect I live in north east London)
I'm sorry to sell it but my newly built long wheelbase 0-6-0 needs larger radius curves.
