In 1984, a Class 141 unit was built for trial running in Malaysia and Thailand. The unit was re-gauged to metre gauge. The trial running wasn't successful.undefined The vehicle was different from the twenty British trains having only longitudinal seating for 120 passengers and space for another 140 standing. Only 1 car was powered with the other being a trailer vehicle. After the unsuccessful trial in Thailand the Pacer went to Malaysia and then to Indonesia for further evaluation. It was last seen outside the Ulu Yam station, on a railway siding, in Malaysia in fairly derelict condition in 2000.

At the end of their career with British Rail, 12 units were sold to Islamic Republic of Iran Railways and were exported during 2001/2002.undefined with two spotted in service in 2005, All units have since been withdrawn and replaced by new DMUs. Two units (106 & 112) were exported to the Netherlands but they are not currently being used. Some units remain in the United Kingdom with two units in preservation: 141108 at the Colne Valley Railway, and 141113 at the Midland Railway – Butterley. Two units (141103 and 141110) were formerly preserved at the Weardale Railway, of which 141103 and the one remaining car from 141110 were scrapped in March 2018.undefined
