Manx Electric Railway car 21 and trailer 44 stand at Douglas Derby Castle station on 11 May 2017, prior to working the 10:00 relief service to Laxey. This was a last minute addition, after the previous tram was severely oversubscribed. It was such a rush job that the driver didn't actually know whether he would be going through to Ramsey or not, until he arrived at Laxey!
