Both Hornby and Bachmann sets use standard OO/HO track which can be expanded with track from the Peco Setrack range. The locos and rolling stock are also compatible with other brands of British OO models, the couplings are very alike and will connect without problems.
A mains powered controller is supplied, either using a variable 12 volt DC output to control train speed, or in the case of DCC train sets a Digital Command Controller supplies track power and sends digital commands to control each locomotive.
The Hornby Railroad range includes several budget priced train packs ideal for adding another train to your train set. Click here for a full list.
