 On 4 October 1899 the MR loaned the O&AT an eight-wheeled 70 seat passenger carriage.As this had been built for the MR's standard height platforms rather than the O&AT's low platforms, 80–100 ft (24–30 m) of each platform on the Tramway was raised to standard height to accommodate the MR carriage.The Metropolitan and the Oxford & Aylesbury Tramroad Company were cooperating closely by 1899.
