off the top of my head no - i think its erroneous from the original data import - if anything it should be the platform number for that side of the station?

It was a fleeting visit from one side unfortunately - enough to confirm the entire building was a Premier Inn but not to get an accurate shape

They've actually been built now, (I've even been in them), converted them to buildings and given them details :) (although I'm not sure on which building is which out of the 2 new ones)
