A-Track - Your DCC Buddy

A-Track for Windows (A-Track) is a powerful FREE extension to complement the facilities of your NCE Corporation Power Cab or Power Pro Digital Command Control system and to assist you in organising and running your roster of locomotives on your model railroad.

Using an NCE Power Cab system (including systems based around an NCE SB3a or SB5 Smart Booster unit, or the entry-level DCC Twin), A-Track connects via an NCE USB Interface unit, as shown in the example set-up below for a Power Cab system -

Alternatively, with an NCE Power Pro Command Station, A-Track connects via a standard Serial Port, if you have an older PC which is fitted with one, or via a USB Port and any readily-available USB-to-Serial (RS232) converter unit, as shown below -

When used with either an NCE Power Pro, a Power Cab or Smart Booster Version 1.65 system, or a DCC Twin (and a Version 7 USB Interface where appropriate), A Track will also let you monitor, set up, save, and restore the complete status and operational parameters of the NCE Command Station and all attached Cabs from your PC

Note, however, that these set-up facilities are not available when A-Track is used with the earlier Version 1.28 of the NCE Power Cab and Smart Booster systems, or with a Version 6 USB Interface.

Control and Monitor Your Layout

As well as handling locomotive decoders, A-Track also lets you program and operate accessory (or stationary) decoders, primarily to control turnouts on your layout. To make operation as simple as possible, A-Track allows you to construct an on-screen graphical view of all your layout turnouts, such as that shown in the two example panels below –

Protect Your Decoder, Command Station and Handheld Cab Setups

With NCE Power Pro and Version 1.65 Power Cab systems, A-Track gives you full access to the Command Station, and the ability to display all of the key parameters stored in its internal memory on the PC screen –

Given the current size of hard disks and the amount of RAM fitted in a modern personal computer, there is no practical limit to the number of different Command Station, Cab or decoder setups which can be saved to, or restored from, the computer’s permanent or removable storage. A Track can handle equipment roster lists stretching to hundreds (or even thousands) of equipment items. However, such large lists tend to be unwieldy to view and manipulate, so it is usually easier to compose and save shorter rosters – corresponding, for example, to an operating session.

Additional Facilities

A-Track can handle simultaneous connections to several Command Stations where, for example you use a Power Pro to run your main layout and have a Power Cab connected to the programming track. In such a case, you can have two instances of A-Track running on your computer at the same time, allowing you to switch from operations to programming, and back again, at the click of a mouse.

As well as its primary purpose of storing and manipulating the contents of DCC decoders and your Command Station, A-Track also allows you to control any selected locomotive or set of turnouts on the main track directly from the PC, using the mouse and a ‘soft’ on-screen controller to issue DCC commands directly to the NCE Command Station. Although this control function is really intended as a test facility, to check the results of programming a locomotive decoder, for example, you can call up and operate as many as eight ‘soft’ controllers on the screen simultaneously - if you think you possess the capability and dexterity to run eight locomotives simultaneously on the layout by yourself !
