Just reckoning up following the chat about the 15, to see if it would be possible to send one via Langley Park and tweak the 13, 14 and X25 as a result.
13 - merge with 15a.
14 - as is.
15 - as is.
15a - as is to Langley Park and then the 13 route to Durham.
X25 - The section between Sacriston and Langley Park goes via the 43/44 route to Dryburn and back out via the 15 route to Langley Park.
Or something along those lines...
