Train control is what lets you move beyond simply sending power to the rails. A basic setup might run one train with a transformer or power pack, while a more advanced system can handle multiple locomotives, sound, lights, accessories, turnouts, and wireless operation.
Trainz carries train control systems for sale for traditional layouts, modern command setups, repairs, and upgrades. Inventory changes often and may include:
For many layouts, control starts with the device in your hand or on the control panel. Traditional O Gauge, S Gauge, and Standard Gauge trains often use AC transformers, while many HO scale and N scale railroads use DC power packs or DCC throttles.
These pieces are useful when replacing a failed controller, restoring an older layout, adding another operator, or upgrading from a simple loop to a railroad with more movement.
Modern command systems let operators control more than track voltage. They can manage locomotive speed, direction, lights, sound, smoke, couplers, and accessories depending on the train and electronics installed.
The right system depends on your scale, locomotive electronics, track type, and whether you want conventional control or command control.
A decoder is the small electronic brain inside a locomotive or accessory. It receives commands from the control system and tells the train what to do.
Before buying a decoder, match it to the locomotive, motor type, available space, power system, and control system. A decoder that works perfectly in one engine may not be right for another.
Control parts are often needed when a layout grows or when older electronics begin to fail. A replacement board can bring a locomotive back to life, while an added throttle or wireless controller can make operation easier.
Trainz inventory may include new arrivals, pre-owned control parts, vintage components, estate finds, new old stock, and hard to find electronics for older and newer systems.
A train control system is the equipment used to run model trains and accessories. It can include transformers, power packs, throttles, command stations, decoders, receivers, transmitters, boosters, and wireless controllers.
DC changes track voltage to control speed. DCC sends digital commands through the rails for independent locomotive control. Lionel TMCC and Legacy are command systems used with many Lionel trains. MTH DCS is a command system used with many MTH locomotives.
A decoder receives commands and controls locomotive or accessory functions. Depending on the decoder, it may control speed, direction, lighting, sound, smoke, couplers, turnouts, signals, or other features.
Not always. A simple DC or AC layout can run well without DCC. DCC is useful when you want to control multiple locomotives independently, add sound and lighting features, or operate a more complex railroad.
A transformer supplies power and often controls speed on traditional AC layouts. A throttle is the handheld or panel control used to adjust speed and direction, especially on DC or DCC systems.
Many older locomotives can be upgraded with newer wiring, decoders, sound, lighting, receivers, or command boards. Compatibility depends on the locomotive, motor type, available space, and control system.
Some Lionel and MTH trains can run together in conventional mode on compatible three rail track, but advanced command features usually require the correct system, such as Lionel TMCC, Lionel Legacy, or MTH DCS.
Yes. Trainz inventory may include vintage transformers, pre-owned throttles, command control parts, estate finds, new old stock, replacement circuit boards, receivers, transmitters, boosters, and hard to find train control components.
