The bus broke down in Whickham which must have been a different service. The 2100 was lost mileage? Do you mean it didnt run at all or it ran in part. HELP
"Lost mileage" is basically the amount of service lost due to the breakdown. It's a really technical term that should really be avoided online!
Edit: Jamie has beaten me to it.
