There was a lovely GWR wooden goods shed before the Oxford Rd bridge ,also the farm equipment on flat cars ,and a regular newspaper train with a Hymeck on the front ,plus the regular parcels to Northampton usualy pulled by a 25 .We had a real mixture of units at the end of BR operation due to the regular units falling apart daily ,Marylebone grabbed anything that would move and some that tried but didnt!The old loco shed was still about but derelict ,became a wharehouse now flats,I agree about the oil depot never saw a single wagon there .By the way the Risboro MRC looked into renting the wooden goods shed as a club room but BR didnt want to know they had other ideas and were in cahoots with the council.Dont forget the station entrance was on the front of the building not were it is now ,the regular ticket collector was a great guy and only passed away a few years ago.The buildings in great Western St were very interesting in design all swept away now of course one was a pub and another became a wholesale newsagents depot.Have a look in the Old Aylesbury books there are many photos of the station in them,the Bucks Herald newspaper have the details.
