TCS Command Stations

This page is a generalized summary of the CS-105 and LT-50 command stations. For more information, please visit our Documentation Wiki.

The TCS command station brings DCC to the modern era by leveraging recent technology and industry developments. Layout Command Control (LCC) and RailCom® support enables consistent bi-directional communication between your locomotives and peripheral devices.

The CS-105

The TCS command station also includes out-of-the-box support for wired throttles via an on-board RJ-11 connector. You may use this connector to interface with several different kinds of wired throttles, including NCE, Lenz, SystemOne, and more! Support not only includes literal hard-wired throttles, but also wireless systems such as those offered by NCE, or third-parties such as WiFiTrax. The TCS CS-105 command station is rated for 5 Amperes of continuous current, but can be throttled back via user configuration to suit your needs. Especially for smaller layouts and scales, the system can still supply all of your Z, TT, N, and HO locomotives without boiling their shells! For lager scale enthusiasts in G and O scales (narrow gauge variants included), add-on boosters will keep your workhorses steaming ahead no problem!

  • 400mA output current per LCC port
  • Built-in WiFi LCC computer interface

Power Supply Selection: When selecting a power supply voltage, you choice should depend on two factors: 1) Modeling Scale 2) Maximum loco speed. For smaller scales such as Z, N, TT, etc., the 12V supply is recommended. The 12V supply is also acceptable for larger scales such as HO; however, if you like to run your trains at higher speeds the 15V supply increases the maximum voltage available to the motor, allowing your models to reach higher top speeds. This is particularly beneficial to modelers of bullet trains and other high-speed passenger services. Both power supply options are rated to supply the CS-105 with up to 5 Amperes of continuous current all day long!

Small Package; Big Power

The CS-105 is not only feature-packed, but also highly capable with plenty of horsepower for your railroad. The CS-105 has a user-configurable short circuit protection algorithm and current limit up to 5 Amperes. Unlike many systems on the market, when we say "5A continuous" we mean it! The CS-105 can supply up to 5 Amperes of current to your railroad all day and all night long. The CS-105 can also simultaneously operate up to 260 individual locomotives (consisted or solo) thanks to a highly-intelligent packet handler and "stack" management algorithm.

Auxiliary Boosters

5 Amps not enough? We understand. That's why we offer auxiliary boosters such as the B-106! Expand out your current capacity while maintaining your RailCom® network using the LCC-enabled B-106 auxiliary booster. Already have a large layout with boosters you don't want to upgrade yet? No problem! The CS-105 can be integrated into existing ecosystems such as Lenz, NCE, Digitrax, and more using our Booster Adapter (sold separately).

Multiple Connection Modes

The CS-105 can be used as a standalone access point for WiFi throttles such as the UWT-50, but can also connect to an auxiliary AP (router) to expand the network and maximum number of throttle connections. In addition to WiFi throttles, wired throttles such as the LT-50 and T-50 wired LCC throttles can be connected through the LCC Can Bus. But that's not all! The "Aux Cabs" jack on the CS-105 allows you to connect and use some other manufacturers' throttles (such as NCE, Ramtraxx, SystemOne, and more) with the CS-105. Add-on devices such as the "LCC-LocoNet Gateway" from RR-CirKits can also be used to interface Digitrax throttles and a PC.

LCC Integration

LCC Bus connections on the command station allow for direct interfacing with LCC layout devices and modules. You can communicate with any LCC system to control switches, adjust layout lighting, and anything else that the LCC bus is connected to.

RailCom® Integration

RailCom enables bi-directional communication between the command station and decoders. This allows for read-back of CVs while programming on the mainline. The inclusion of RailCom opens up significant opportunities for future features and expansion.

Consisting doesn’t have to be difficult, intimidating, or complicated! The CS-105 features a simple consisting interface where users can make, modify, and break up consists in mere seconds. The CS-105's consisting system also features new and unique configuration options for consisted engines which will make your consisting experience more realistic than ever without having to spend hours setting it up!

Full-Text Menus

The settings of the CS-105 can be accessed through a TCS throttle or JMRI. Configuration menus and options are listed in full words and phrases. No guess work or manuals needed! Use the [?] button on the TCS throttle keypad in any menu to access help text for that menu item. The throttle will display a simple description of the highlighted option. Help is always one button press away!

Programming Options

Take advantage of several different programming options with the TCS Command Station. RailCom® programming on the mainline allows for live CV read-back without the need for a dedicated programming track! Or, you may use an isolated programming track to use Direct or Paged mode programming. The TCS CS-105 Command Station does not require an add-on "programming booster" for programming operations, unlike some command stations offered today, and older-generation systems available in the past.

When programming a decoder, the TCS throttle can display information about the CV down to the individual bit, giving users the ability to further understand and visualize CV's, and manipulate them at the bit level, which is especially useful for CV's used to configure multiple options, such as CV29 or CV61. In addition, when using a TCS throttle, you may press the Help button after entering a a NMRA standard CV number to display a "plain text" explanation of the CV and what it does.* TCS is striving to offer the most user-friendly programming interface possible, while not compromising the operational capabilities in favor of "simplicity."

Easily Updatable
