Nice Marx Die-Cast Metal Columbian locomotive with plastic tender runs well forward & reverse and the smoke unit works, the headlight and number-board do light.   The term “double reduction” means that there are two steps in the gearing. The motor runs at a higher rate for any given speed.   That means these locos typically move a little slower, run a little smoother and can pull more cars than a single reduction motor.   A second effect is that the gear attached to the drive wheels has a smaller diameter. That makes the thickness of the flange a bit less and makes it possible for those locos to travel through some other brands of switches.   

The 666 engines have die-cast metal shells which provides more Adhesive Weight. Which is that part of a locomotive’s weight that is supported by its driving wheels. In the case of modern Bo-Bo and Co-Co diesels and electrics, 100% of their weight is supported by their driving (or driven) wheels which allows them to deliver a very large starting Tractive Effort.  The same applies to 0-6-0T steam engine, however with 0-6-0 tender engines, perhaps no more than 70% of its total weight may be supported by its drivers. The greater the number of carrying wheels, the less weight is available for adhesion, and in the case of a typical Pacific locomotive less than 50% of total weight may be available for adhesion. This has serious consequences in terms of limiting the locomotive’s wheel-rim tractive effort and its Drawbar Power. A locomotive’s starting tractive effort only provides an indication of the size of train that it can start. It does not measure the ability of the locomotive to pull a train at speed. This is because tractive effort reduces as speed increases. A locomotive that can maintain a high tractive effort at speed is a more “powerful” locomotive than one that cannot since Power = Tractive Force x Speed.

The relationship between TE and Speed for a variety of locomotives is illustrated in the diagram below (copied from page 499 of Wardale’s book "Red Devil and other Tales from the Age of Steam" in which it can be seen that the TE of the “Super Class 5 4-6-0 (5AT) remains higher than even the most powerful British Pacifics once their speed exceeds 70 km/h. The 5AT’s ability to maintain high TE at speed is a measure of its ability to deliver and make use of steam that is supplied to the cylinders i.e. “good breathing”. (The diagram can be compared to the Power - Speed Diagram -copied from the same page, which is shown on the Drawbar Power page of this section of the website.) - 5AT-CO-UK.  

The MARX 666 was also a best seller and was produced from 1955 to 1974. Its production was briefly halted between 1961 and 1967. One of the most highly cherished collectible trains, the Marx 666 is the favorite of all collectors worldwide. It had a 2-4-2-wheel arrangement and was an O Scale model train. It came in the traditional black color with stripes on the boiler walkway and smoke cylinder. Some of the rarer variations in this model train were the army green color that was produced only for two years and the grey locomotive which was only produced in 1971.  This train had an immense amount of fine detail and style and was in high demand amongst collectors and train lovers in America. -EzineArticles
