London Underground Sleet Locomotives - Sleet Tender ST1 / ST2

Sleet Tender ST1 / ST2

In 1957, two experimental sleet tenders were built at Acton Works, for testing on the Piccadilly Line. One tender was attached to the front of a regular tube train while the other was attached to the rear. The tenders were low so as not to obstruct the driver's view. The experiment was not a success, however, because the signalling had accurately positioned block joints, which operated train stops. The extra length of the train with the tenders attached would have required significant alterations to the signalling system, and the advent of de-icing gear attached to regular service trains followed soon afterwards.
