Services run south to Oxford, 5 miles (8 km) away, and north-east to Bicester Village and London Marylebone.

From 1 January 1968 [1]British Railways withdrew passenger services from the Buckinghamshire Railway between Oxford and Bletchley and closed all intermediate stations including Islip;[2] In 1987 Network SouthEast reintroduced passenger services on the Oxford to Bicester Line and on 13 May 1989 Islip was reopened as a single platform unstaffed halt.

[1] The station closed to rail traffic on 15 February 2014 (the last trains having run late on 14 February) in order to allow upgrade of the line between Oxford and Bicester.

The rebuilt Islip station has 2 platforms, with a car park for 23 spaces.

This was in advance of the new London Marylebone to Oxford service which was due to start in 2013,[5] but was later delayed to 25 October 2015.
