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.

Analog Conversion is a Power Conversion Mode supported by most Multifunction Decoders. It's an optional feature. DCC signals will damage coreless motors.

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.

Short Circuit A Short Circuit gets its name from the electrical energy finding a shortcut, an easier path from one side of the power supply to the other.

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.

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.

Pulse Width Modulation Pulse Width Modulation (PWM) enhances motor control. Instead of applying direct current (DC) to the motor, a series of pulses is employed. These pulses reach their maximum power for a brief period. Va...

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.

Wiring a Programming Track for DCC A Programming Track safely programs Multifunction Decoder using Service Mode Programming. It’s easy to have a portion of your layout’s track double as a programming track.

Not sure what it is a Program Track. but many seem determined to wire it to ensure damage, so here is the proper way to wire one.
Program Tracks work in Service mode, so the decoder's address is irrelevant.

May 17, 1930: the Canadian Locomotive Company delivers No. 7700 to CN, the first diesel-electric switcher ordered by a Canadian railway. Most of the locomotive's internal diesel-electric components came from the Westinghouse Company; assembly was done at CLC in Kingston. 1/2
