Non Powered?

In the section on locos converted to train-heating units the conversions are described as `non-powered', but surely the engines were kept otherwise they could not have functioned as heating units. Is `non self-propelled' really meant here? Barney Bruchstein (talk) 10:02, 29 April 2014 (UTC)

They are first mentioned in

• British Railways Locomotives and Other Motive Power: Combined Volume. London: Ian Allan. 1970. p. 49.

as "non-powered carriage-heating units". This description continued for the next few editions, but in

• British Rail Motive Power Combined Volume 1982. Shepperton: Ian Allan. April 1982. p. 52. ISBN 0-7110-1230-X. CEX/0482.

they became "Non self propelled". The similar term "not self propelled" first appears in

• British Rail Motive Power Combined Volume 1978. London: Ian Allan. April 1978. p. 48. ISBN 0-7110-0851-5. CEX/0478.

for some former Class 08, Class 35 and Class 42 locomotives. These two variants seem to be used indiscriminately in the subsequent editions. --Redrose64 (talk) 11:01, 29 April 2014 (UTC)

Road Switcher?

Should we call it a road switcher since it is designed for both mainline freight and yard switching duites? — Preceding unsigned comment added by 73.93.152.192 (talk) 22:53, 20 December 2018 (UTC)
