Occasionally in the 1980s, a DMU would be booked for a fairly rapid return from Oxford, and would therefore arrive from the London direction into the up platform, instead of the usual down platform. In order to do this, it would cross over at Hinksey, and use the bi-directional loop. L594 (51104, 59435 & 51073) is pictured doing that on 14 March 1987 with the 2F38 12:49 Paddington to Oxford service, which because of its 11 minute layover at Didcot Parkway, had changed headcode to 2C26 at this point.
