2024 capacity upgrade

In December 2018, NIR announced that 21 additional carriages would be purchased from CAF to extend 7 units from the Class 4000 fleet to be 6 carriages in length. Both platform 1 and 2 at Derriaghy were too short (only 3 carriage trains could call at the station) and each platform needed to be 150m in length, so the decision was taken to extend the Lisburn-end of platform 1 but rebuild platform 2 across the Queensway road with a ramp to make the station fully accessible.

A planning application was submitted to Lisburn and Castlereagh City Council in March 2021, of which approval was given in October 2022. Consequently, construction commenced July 2023. The new platform 2 opened on Monday 25 March 2024, and all works are due to be completed by Spring 2024.
