Athearn Genesis Challenger on 18 Inch Radius
Roland asks this question:
“I plan on buying a pre-loved (I presume that means 2nd hand but used with care) HO Athearn Genesis Challenger. Due to where it is, I will need to buy it untested. From the pictures and description, it does look to be in good condition, and the price seems fair considering what they go for new. My research tells me a 22-inch radius is recommended, but I only have 18-inches. Does anyone have any experience with running this model on less than a 22-inch radius, and what’s the general opinion on the Challenger?”

Thoughts on Atlas Code 83 Track
Wayne posted this question:
“It’s taken me a while, but I’m now at the point of buying track for my first HO layout which will be 9ftx4ft. My cousin uses Atlas code 83 track, but before committing I would like other people’s thoughts on what track would be best? Does it come down to personal preference, or is one track better than another?”

Can I Fit a Decoder on My Own?
David Thompson author of the DCC Help e-book contributed this article to share:
Can I Fit a Decoder on My Own?
Yes, you can! Installing a decoder on a locomotive is not a very difficult task, once you get the hang of the basic concepts involved in its operation.
However, it is advised that the first time you operate on a DCC layout; you get a decoder-fitted train to work on the model.
This will give you some time to learn about the working of the equipment and get familiarized with it before starting from scratch. Once you attain the knowledge and get familiar with the working criteria, you are all set to try the installation on your own!
In a nutshell,
• Decoder is like the working muscle in the DCC layout.
• It is responsible for assigning an address or loco number to the train.
• It also detects the signal incoming from the command station on the track rails and decodes it into the requested action for the locomotive.
• The decoder commands and powers up the motor for controlling its speed and basic direction settings.
• Optional commands that can be controlled by a decoder include controlling the back EMF and momentum and updating the speed table.
• The decoder also acts as a switched outlet and functions to power up the additional equipment like the driving headlights, any special light effects, and the sound.
• It is packaged as a chip, ready to be installed in the locomotive with a ‘plug and play’ action. Many locomotives also come with the ‘DCC fitted’ option, which means the decoder is already installed in them and they can be used as it is by the user. Such systems are ideal for beginners. Advanced users can program and install the decoder themselves as well for defining more custom functions and features.
• The price for the decoders depends upon the number of features it offers.
• When selecting the decoder, it is a good idea to go for NMRA compatible models so that they can work in conjunction with any throttle or command station you are using. Also, look at the power consumption of the decoder before adding it on to your locomotive.
• You can easily install and fit a decoder on your own, but opt for assistance from a friend or a technical professional in case you are confused about the different steps involved. You can also seek online help in this regard, there are a number of resources available that guide on the model and type of decoders that you should go for.
• There is no specific decoder that can be termed as the best choice for your locomotive. Different versions and brands seem to work for different people. So, at the end of the day, it is all about what you seek from the equipment and your own requirements that make the layout work like a charm for you.
Easy Way to Make Unpaved Areas
Neil sent in his quick tip:
“I discovered an easy way to make unpaved areas of ground surface such as gravel or sand. I now use differing grades and colors of sandpaper and adhere to your surface. I wish I had found out earlier. That’s life I guess.”

Brushes for an AHM Trolley Motor
Bruce asks:
“I am searching for brushes for an AHM trolley motor. The originals burned – sizes are 2mm x 3mm and a guess of about 5mm or 6mm long, and of course, with springs. I searched eBay, googled the world…but cannot find any sources. The question: does anyone know where I can find some? Thanks in advance for your help.”
Preferred Track for Beginners Layout
Andy sent in this question:
“I am planning an 1800×1200 (6×4) N scale layout of logging & mining operations. It has been almost 40 years since I last had anything to do with Model RRs. What is the preferred track type for use that is available in Australia? Thank you in anticipation.”
Engine Maintenance
Frank asks:
“I have several HO engines that have been in storage for a number of years and now will not run. Are there any recommendations as to how to clean or lubricate them and is there information explaining cleaning and maintenance issues?”

Signal Pilot to Control Railroad Crossing Lights
Ed models HO scale and asks readers:
“Can anybody tell me where or how to get a manual for a signal pilot to control railroad crossing lights? The one I have is in German and I don’t read German. I need all the info that I can get.”
Electrical Block Detection
Paul models HO and asks:
“I am still building my 5 module layout and plan to use electrical block detection in the future. I will run DCC NCE and operate a complete loop with an isolated section for each module as well as a siding. I want to include lights to indicate if the track is occupied or not. I would appreciate any thoughts on what I’ll need to make all this happen. Thank you in advance.”

Loco Speeds For Consists
Jamie is into N scale and posted this question:
“Is there a decoder that can regulate the speed of a loco in a consist? I only have two engines… an Atlas and a Kato… but the speeds don’t match well. I don’t want to risk damaging them. Any suggestions?”
