Apologies if this is in the wrong category.
I'm assuming RTT pulls the miles and chains data off Network Rail systems along with timings etc. Is there any reason why that doesn't always for some trains?
An example it doesn't is this one (1S12 10:30 KGX-EDB) -

Whilst one on the WCML (9S54 08:40 EUS-EDB) does -

I thought it might be the distance, but the Euston route is longer. It's nothing to do with the TOC as other LNER trains appear with the mileage data.
I know I can use RailMiles Mileage Engine, but even for a KGX-EDB that won't work as one enquiry as it defaults to the shortest route which is bypassing York station platforms. So you have to double check the route it returns and if necessary, split it up into smaller sections then add it up.
Thanks.
