If mainly local to CLS, a half hourly or hourly extension of the 21 to Langley Park would be best suited. But if demand is mainly to Newcastle, extending the X30 would be a better option with the X31 also replacing the 6 between Lanchester and Stanley. An extended X30/X31 with a PVR of 5x would also give that reliability buffer too.
Not sure the X30 would be the best idea, as you'd leave Sacriston and Witton Gilbert without a service and they're both quite big places really compared to the nothing between Lanchester and Langley Park.
