Mini review of the ZIMO MX31ZL DCC system.
A bought a ZIMO MX31ZL system a while ago. I will try to tell you all what I think about it.
Let's start from the beginning. I once owned a NCE Power Cab. I bought it just to be able to test run all the locos I bought. The plan was to buy a wireless system in the future. I talked to NCE support about this and they told me that NCE will release a wireless system for europe in about a year. That was good news because the frequencies used in the US are not allowed in Sweden. So I can't just import and use a wireless system from the US. But after a year NCE suddenly told me that this was not going to happen. I'm very disappointed. So I sold my NCE system and I will never go back.
I discovered ZIMO and their wireless system for europe. It had been on the market for many years. ZIMO DCC systems are expensive. But it's also the best DCC system on the market. You get what you pay for. One nice feature is the display that can have three different colors depending on the mode.
GREEN background – LOCO MODE.
RED background – SWITCH MODE.
YELLOW background – INPUT MODE: Address, menu, list of names, programming and more.
ZIMO MX31ZL is much smaller then the Power Cab. Dimensions Wfront – Wrear x Hfront – Hrear x L ................ 58 - 69 mm x 23 - 39 mm x 150 mm. It weights only 135 g. Here is a picture so you can compare it to the size of my hand:

It's possible to buy a wireless Cab (MX31FU) and connect it to the MX31ZL. MX31FU looks similar to the ZL, the only difference is a small antenna. This is my plan. I will use the MX31ZL as the stationary (switching) cab for North Yard and the wireless cab for the rest. I will also use ZIMO's train running software. I can then do OP sessions with myself, a friend and the computer takes care of the rest. It takes a while to learn this system, but you will not outgrow it.

Stabilized track power of up to 4 amp continuous and up to 5.5 amps peak, without an additional booster.
Short circuit shut-off adjustable from 0.01 second to 10 seconds.
Adjustable track voltage from 10 - 22V (max. 19V with 90W power supply).
The track output can be connected to the main track, programming track or to a decoder update track (the MX31ZL is also a useful decoder update module).
Built-in volt/amp meter display
USB “client & host” interface for easy PC connection or to plug in a USB memory stick for decoder updates without a computer.
Built-in global RailCom detector for bidirectional communication (RailCom is a registered trademark of Lenz GmbH). RailCom responds to and displays messages in real time for each actively controlled engine (i.e. actual speed, expected stop time, power consumption) and of course allows decoder CV’s to be read on the main. This feature requires RailCom enabled decoders, which at present (Fall 2007) are available from Lenz (only Gold series) and ZIMO (all types). Other manufacturers are expected to follow in 2008. The use and application of the RailCom technology has only scratched the surface and many new features will be added in the month and years ahead. In order to access those new features, the equipment involved (MX31ZL, MX31...) as well as decoders must be updated periodically with new software (ZIMO components in general can be updated without removal or replacement of decoders, EPROMS etc.).
All features of a “normal” MX31 cab.
System expansion with up to 5 more MX31 cabs, radio cab or integration of the MX31ZL in a “large ZIMO system” (with regular command station).
The MX31ZL comes with its own power supply, plug-in panel, USB computer cable, USB adapter for memory stick and operating manual.
