The problem appears to be this record in the Darwin location reference data.
LocationRef tpl="BRSTAP3" crs="BWE" locname="BRSTAP3"
The location name is the same as the tiploc code which isn't user friendly. Other bus/rail stops in the reference data have more descriptive names.
It appears that Network Rail Corpus has a better name, but rather than chopping and changing station by station, it looks to me like it would be best to fix the locname in Darwin location reference data. Is this the best place to request that, or is there a more specific contact? I can see lots of reliable services propagating this tiploc code as the station/stop name
