Summary Wangrow Electronics was an early entrant producing DCC systems, commonly named the Wangrow SystemOne. The founder, Don Wangrow, passed away in June 2003. Wangrow Electronics ceased trading and was dissolved in 2003.

The Wangrow SystemOne was shipped in late 1994, retailing for $879. In 1995 Wangrow announced a 4A seven function decoder for large scale locomotives.

While it has reached end-of-life and is no longer supported, the Wangrow SystemOne is still a good system for those looking for a DCC system. It was a full-featured product in its time, and is still useful. Even used, they are still a good buy.

Wangrow Electronics SystemOne


The SystemOne DCC was also known as the SYS1.

The SystemOne was originally in the design stage by a third party contractor which also manufactured the hardware. The software was supplied by the founder of NCE, who would also supply some of the hardware designs, such as the command station. The dual booster, MasterCab/Procab throttles and decoders were designed by the contractor, as was the cab bus using a 1/4" phone plug. Another manufacturer designed and supplied accessory decoders.

Wangrow would begin shipping their SystemOne (SYS1) systems in 1994.

The SystemOne consisted of the CSP-01 command station and SRB-01 booster and block reverser. A WCT-01 walk around controller was also included. Additional boosters were $249.50, throttles $183.50. Later the WCT-31 intermediate and WCT-11 throttles appeared.

NCE would design and build the command station, the Engineer throttle, and the 10A booster. NCE would soon release its own DCC system under the Master Series name, based around the SystemOne components, in the spring of 1995. The 10A booster as also sold under the Master Series and SystemOne brands.

In 1996 Wangrow released software in the form of Commando, which could restore the command station's settings, and LocoCommand, for automating layout operation.

Many of the parts used to construct their systems were OEMed from NCE. NCE did much of the design, software and construction for the Wangrow SystemOne, in fact, some early NCE systems shipped with Wangrow's SystemOne manual, as it was the only one available at the time.

With the introduction of the NCE PowerHousePro, NCE became independent of Wangrow for sales. NCE offered Wangrow the system, but he passed on selling it. NCE felt that new products arriving from companies such as Digtrax benefited from advances in technology, allowing them to offer a superior product at a lower price. NCE wanted to sell the PowerHousePro at a competitive price. NCE decided to sell at the same price as the SYS1 to avoid undercutting their former partner. By integrating the command station with a single 5A booster it would be possible to retail the system for 30% less than a SYS1.

In 1999 Wangrow Electronics began development of their own software and radio throttles. A 10A system also appeared for $909.

Don Wangrow failed to recognize that NCE owned the command station software, as well as the software for the throttles, and when the agreement ended he could no longer sell command stations and throttles. in 1998 NCE decided to go their own way and would no longer supply ROMs for the Wangrow SystemOne. Without NCE's software licence, Wangrow had to develop their own software, by hiring people without any knowledge of DCC systems (specifically NCE's software) to avoid legal issues.

Developing software began to impact Wangrow's cash flows, making it difficult to pay for other products they could sell, which meant they could not supply their customers. They could not sell any SystemOnes without new software. The final SystemOne ROMs were manufactured in April 1999, after which no more SystemOnes could be manufactured without new software in their ROMs. Wangrow was unable to develop their own software, which doomed the enterprise.

With the death of Don Wangrow in 2003, the company was soon closed and dissolved by the investors.

RamFixx Technologies

RamFixx Technologies was a Canadian company based in Mississauga Ontario.

Richard Wendt was a model railroader who operated a business called RAMFIXX Corporation which sold RAM (memory) upgrades for computers. In 1995 he decided to build a DCC system. He needed expertise so he collaborated with Wangrow and NCE to develop, manufacture and market his Ramtraxx DCC System.

RamFixx introduced the RamTraxx DCC system, based around the Wangrow SystemOne and NCE technologies, in 1996. The RamTraxx system featured a new innovation: both the command station and booster in the same package. By combining both devices into one integrated unit, RamFixx was able to reduce the cost by 20%. Neither the SystemOne or NCE Master System offered this, both manufacturers used separate command stations with external boosters. Some of their RamTraxx advertisements claimed their system was the affordable choice. The Ramtraxx system was also unique with dual 5A boosters. Dual boosters were another innovation, but a software bug resulted in a shutdown of both if one booster operating in autoreverse mode encountered a short circuit condition.

Like Wangrow, RamFixx used the services of an OEM to manufacture the product, with NCE supplying the ROMs with the software needed.

RamTraxx offered an upgradable EPROM, total compatibility with SystemOne, and the ability to also use boosters from Lenz and Digitrax. Other features included addresses up to 9999, 250 locomotives or consists, up to 63 cabs, and 14/28/128 speed steps. One interesting feature was the keyed lock on the command station/booster. In terms of features, RamTraxx and SystemOne were full featured, top of the line systems in their day.

A complete system retailed for $689.95 in 1997. A basic system was $359.95, decoders were $44.95.

The system was marketed in 1996, and a few years later RamFixx Technologies closed. Wangrow Electronics purchased the assets in 1998. RamFixx lacked the resources to support and service the product line, ending with the sale of their DCC assets to Wangrow.


Wangrow's SystemOne appeared in mid-1994, with features such as four digit addresses, from 0 to 9999, programming on the main (POM), advanced consisting, and a data port (RS232) for easy interfacing with a computer.

Wangrow SystemOne command stations can be interfaced to a computer if it has the RS232 interface. The SystemOne is supported by JMRI.

Optional Analog Throttle

Some SystemOnes were equipped with an optional analog throttle adapter. A standard nine pin serial cable will not work. See the User's Manual for instructions on making a custom cable.


Adjusted for inflation, the US$879 price in 1994 is equivalent to almost $1500 today (2018).

Last Software Update

See the NCE Website.

The last updated EPROMs produced by NCE for the Wangrow SystemOne were Version 12/21/04, December 2004. An updated manual was produced as well.

NCE announced that this would be the final upgrade they would provide for the SystemOne.
