We have a range of DCC control systems available, suitable for any DCC application. Bachmanns' EZ-Command system offers excellent functionality at a budget price with up to 10 locomotives. We recommend this unit for those wanting to try out DCC and for starter layouts. The new Dynamis system offers the full power of DCC, able to operate hundreds of locomotives and accessories from wireless handsets, ideal for walk-around control. Hornby offer the Elite controller, equiped with two control knobs this system makes it easy to control two trains at once. Finally, for those wanting to exploit the full flexibility of DCC we have the Lenz range available with the option of LH90 with a control knob, or LH100 using push-button control, ideal for those with expanding layouts and locomotive fleets.
Most DCC controllers can supply sufficient current for two trains, however as your layout expands and you have more trains running you may find you need to supply more power. The additional amplifier or booster unit is used to provide a greater current than the controller can supply alone.

Lenz LT100 Digital/Conventional Junction Module Module (13100)
The LT100 serves to electrically isolate a DCC operated layout area from a conventional DC operated one. The LT100 momentarily breaks the power supply to the conventional side of the layout when the isolation gap is crossed. This protects both the DC power supply and the decoders when the locomotive bridges both sides of the gaps between these two sections. One LT100 is needed for each conventional DC power supply.

Let us assume that you control a part of your model railroad digitally and another part conventionally. For instance you may have a digitally controlled locomotive servicing facility and a conventionally controlled line divided into blocks. If you now drive a locomotive (train) from one part into the other part, then the wheels of the vehicles will create a connection between the 2 layout parts. This connection will lead to a short circuit. Usually the digital system will shut off immediately. However it is possible for the digital and analog systems to combine in such a way that can either damage the analog system or the decoder. It is the task of the LT100 digital circuit breaker module to prevent this. The digital circuit breaker is simply inserted between the conventional transformer (power pack) and the track. If a connection is created by the wheels of a vehicle, then the LT100 module will interrupt the connection between the conventional analog system and the track. This way a short circuit is prevented and no damage can occur. The track is supplied with digital voltage during this time, so that the train can continue operating. Once the train has completely crossed the gap and the systems can no longer be combined the digital circuit breaker will reconnect the analog system. This happens very fast preventing any perceived interruption in power to the track. The result is a smooth transition between different control systems.
