The PEARL and OPAL engines are British saddle tank and side tank designs following the well known Kerr Stuart and Hunslet styles respectively.

JACK is also a Hunslet based locomotive but is of an unusual and distinctive well tank design.

LI'L JO is an American Porter design whilst ARTHUR (special order only) is based on the German Koppel locomotives.

All Maxitrak kits are complete with every component necessary, including every last nut and bolt, to construct the fully functioning live steam locomotive. Kits are designed to be assembled using hand tools only, with no machining required.

Much use of up to the minute technology has been utilised in the manufacture of the parts, including both laser and water jet cutting and C.N.C. (Computer controlled) machining, investment casting etc. Some parts are pre-assembled and complete, such as the silver-soldered all copper boiler which is tested to twice recommended working pressure prior to despatch and is supplied with the appropriate test certificate.

Parts are supplied in a logical build order and can be assembled as the kit progresses. All the locomotives have steel chassis, cast iron wheels, gunmetal cylinders and silver soldered boiler.

The builder will require a good selection of spanners, drills, files etc to complete the kit. Cylinders are fully machined and only require the studding, gaskets, rings and packing to be assembled before fitting to the chassis. A full list of parts and a build manual are supplied
