6172 done a round trip on the X1 from the galleries to Newcastle this afternoon

As 6376 has remained at Consett, 6099 is the dedicated spare bus for service X1. You'll find it being allocated to service X1 more often than not, so I'm not sure it has a place in this thread!

After 6099 and 9119, 6172 is the next preferred spare for the X1 (although you'd like to hope that there won't often be more than two StreetDecks off service!)
