Some of the steam sappers were fitted with railway wheels. Yeatman records steam sappers numbers 3–7 as being 2-2-0T locomotives on the Lodge Hill and Upnor Railway. Yeatman's editor, Mullett and Nowers disagree. Aveling-Barford have checked their records and have no records of any steam sappers being supplied other than for road use. Nowers states that sapper number 9 was fitted with railway wheels for a trial and that sapper number 12 was purchased with them. In the table below possible railway use is recorded, in all cases this would be upon the LH&UR.
