This folder and the following nine folders contain images of the ATP route buses in blocks of 50 numbers. They are numeric 300 - 349 / 350 - 399 / etc etc. The reason for no prefix to the id is because if the standard prefixes ie DBY / Y-0 / numeric only were used they would not fall into the correct order as the default is set to number order. In some cases the numeric only reg number would not have survived long enough to receive a Y-0 number so it is inserted in the order in which it would have fallen had it survived. There is now a comprehensive selection of buses in original route bus liveries in the folder 'Original route bus liveries' so the few remaining images of this type left in these numerical order folders have been removed and placed into same.
