16/24 H.P.

W/n 5821 in "preservation". Cab is non-standard and engine covers are of incorrect pattern.

 The 16/24 H.P. type comprised two batches of locos that were very different in appearance but were equipped with similar engine types. This was the twin-cylinder Ailsa Craig DF2, CFS2 and later RFS2 diesel of 4-in bore and 5-in stroke. So as far as Motor Rail were concerned they were the same class. Motor Rail were the first customers to receive Ailsa Craig's new monobloc engines, such as the CF, as opposed to the earlier DF engine with separate crankcase and block.

Number Series

5821-5832 (built between 1934 and 1938).

Note: This batch was of the channel-framed variety, using the same frame as the 20/35 H.P. type.  Only one survives in the UK today, this being 5821, now preserved by John Rowlands.

7601-7614 (built between 1939 and 1940). 

Note: These were of the plate-framed variety (like the 20/28 H.P.), and were thought to have been fitted with RFS2 engines. They were visually different to the 20/28 in that they were right hand drive. None survive in the UK.
