Thomas was made using a modified version of a London, Brighton and South Coast Railway E2 tank engine with a chassis of a Hornby Triang Jinty and a distinctive dip at the front, but none at the back.
Thomas was made using a modified version of a London, Brighton and South Coast Railway E2 tank engine with a chassis of a Hornby Triang Jinty and a straightened running plate from smokebox to bunker.
Edward was made using a NBR D34 'Glen' 4-4-0 model equipped with a usual brass kit 3500 gallon Fowler tender.
Henry was made using the Triang LNER A1 class tooling with the firebox cut down and the trailing wheels removed. The front of the running plate was sanded to a smooth round drop and filled with glue that was shaped, as per Gordon MK II. The firebox needed more adapting, so the triangular recesses were filled using plasti-kard and miliput, and the cab was sawn in half at the centre of the side windows, cut and sanded more and finally brought back together again.
The tender was a B12 one with 2 plasti-kard covers on the sides.
New handrails and cab rails are from 0.7mm brass wire and pillars though 0.45mm would have been better. The steps, cab doors and fall plate were pinched from a spare Black 5. Lamp irons, cylinder cock pipes and realistic front couplings were added next. The wheels, tyres and middle pin were changed too.
Henry was made using a LMS Stanier Black 5 tooling with a further forward top feed and a Fowler tender.
