DCCWiki, an online reference for NMRA Digital Command Control for Model Railroads. Created by volunteers for the modelling community. Plus other interesting things related to technology, because we should not forget how we got to where are today.

An overhead view of an HO model railroad section with an ore loading area, a small railway shed, an overhead bridge, seven tracks and three switches. Ore spills, rock outcrops and lack of vegetation dominate the scene.
You would think it would be easy to model a place with very little vegetation but I am finding it difficult. I am working on a nickel mine region, modeling the year 1985 outside of Sudbury, Ontario where nothing grew.

Jun 2, 1995: CN's old electrics operate for the last time on the Montreal-Deux-Montagnes commuter line through the Mount Royal Tunnel. The equipment included Z-1-a, Z-4-a and Z-5-a electric locomotives; EP-59a and EP-69a electric multiple units and balloon-top coaches. 1/3

A black and white photograph of a massive articulated steam locomotive. The cylinders are huge, and the boiler even bigger.
The largest cylinders ever fitted to a steam locomotive were the massive 48"x32" low pressure cylinders on the Virginian Railway's Class AE 2-10-10-2. The high pressure cylinders were also huge at 30"x32". Otto Perry captured #801 at Roanoke VA in 1932.

Why do so many modellers rely on a $0.50 light bulb to protect their expensive DCC systems & locomotives when proper short protection is available?
Pay now or pay later, your choice.

An advertisement featuring a bottle and glass of ale alongside a model train under construction. The ad promotes a blend of hobbies and the enjoyment of ale. CARLING'S Red Cap ALE FULL 12 OZ For 109 years in Canada, now a product of U. S. A., too. Somewhere close by is a man who knows how to enjoy a hobby and a wonderful glass of ale, too. Enjoy the full, delicious flavor of this light, bright, golden ale ... Let the jolly Red Cap remind you to call for Carling's.

DCC Multifunction decoders don't use DC to drive the motor. They create a Pulse Width Modulated signal to control direction & accurately maintain the desired speed.
It really is simple! Repost: spread the word.

Program Tracks work in Service mode, so the decoder's address is irrelevant.
