Digitrax and NCE, the two largest DCC companies in North America, currently exist purely due to market inertia, and not because of the merits of their product offerings.
Digitrax has dug in their heels with proprietary technologies like LocoNet, Duplex, and Transponding over the standards of LCC, Wi-Fi, and RailCom. To be fair, LocoNet is a great technology but ironically, other companies have much better products for it than Digitrax itself. Meanwhile, NCE has barely changed in 25+ years.
Digitrax’s consisting is actually even easier to do, but very limited in functionality, since they are single-ended and you can’t send functions to all units.
NCE’s consisting was by far the most robust and prototypical until TCS beat them at their own game, removing their one remaining competitive advantage. Digitrax matched their ease of use in 2006, TCS and Digitrax both offered robust radio systems in 2020, and in 2022, TCS finally beat them at consisting.
CVP is ancient and quite expensive. You can get the throttles for an XPressNet system, but at this point, I fail to see why compared to using Wi-Fi throttles.
Just use JMRI WiThrottle server.
TCS is expensive, but their stuff is extremely well engineered. If you’re going to pay top dollar, TCS and NCE are the two expensive options, and TCS is superior in every way.
When looking for a DCC system, people should consider all the options out there, not just the two biggest players in North America. The legacy proprietary systems from Digitrax, NCE, CVP, Lenz, and MRC are long in the tooth compared to modern options like ESU, Roco, YaMoRC, and TCS, or alternative systems like WifiTrax, SPROG, and DCC-EX.
