It is located just south of Clontarf Road DART station on the Dublin-Belfast railway line.

However, maintenance on DART units is also carried out at Inchicore Works.

There is no wheel lathe at the depot and as a result, out of service Commuter (29000 Class) DMUs tow DART trains to the Drogheda Commuter depot in order to receive new wheels.

[citation needed] This depot is also used for the change of drivers on the DART line – much to the dissatisfaction of northside commuters, as the depot is 50 metres from the platform at Clontarf Road Station, making it arguably a more logical point at which to change drivers.

Recent cost-benefit analysis has determined that this inefficiency costs the Irish economy c. €750,000 per annum in lost time.
