WHEN Dalmarnock Power Station opened for business in September 1920 it was said to be the largest electricity power station in the UK.

It belonged to Glasgow Corporation, and while some corporations in England were contemplating stations of their own, none of them, said this paper, “will exceed the Dalmarnock scheme, when fully completed, in extent or capacity of output. Through its agency, Glasgow may confidently depend upon an adequate service of electricity at all times, and under all but the most abnormal conditions.”

The station, which stood close to the River Clyde, did indeed serve the city well for decades, and became a highly familiar landmark in the city, but it was closed down in 1977, and was subsequently demolished.

In May 1969 it was announced that a remnant of the power station was itself going into official retirement.

The so-called ‘Thermos Flask’, alias Number 1571, the proud old locomotive that had been shunting wagons at the power station for the last 50 years, was handed over by the South of Scotland Electricity Board, the station’s operators, to the Glasgow Museum of Transport.

The locomotive’s place in the annals of transport history was assured, the Glasgow Herald noted, and in the museum it would be “preserved and cared for in a manner befitting its proud history.”

No 1571 was a fireless steam locomotive and was possibly the last of its kind in Britain.

It was built in 1917 by Andrew Barclay Sons & Co, Ltd, at its Caledonia Works in Kilmarnock, for the Ministry of Munitions, and it was bought for Dalmarnock on the closure of the Gretna munitions factory in 1919.
