Like any major infrastructure programme, the Edinburgh to Glasgow Improvement Programme (EGIP) must achieve many milestones to meet its end goal, in this case running faster electric trains between Edinburgh and Glasgow that are two coaches longer than the current service. On 10 December, the project delivered three milestones in one day, of which one, not visible to passengers, was Millerhill depot. Initially, the depot will service a small number of trains. However, when fully operational, it will be one of ScotRails main stabling points, with many of its 70 new class 385 Hitachi EMUs serviced there overnight. At the depot, trains will be washed, cleaned, toilet tanks emptied, sanders filled, and screen washers topped up and there are also facilities for maintenance staff who may be called to the depot to repair minor faults.
