Rolling Stock Scheduled Maintenance
Patrick asks:
“My collection of passenger and freight cars is growing and it could be time to collate a maintenance schedule of some kind. Wheel sets, weight, couplers, loose parts, pivots, etc. Am I overthinking problems, or should I just look each one over or test for rollability before I put it on the track?”

Bridge Building On Scale Model Railroads – See How
There are many ways to construct bridges and the method used usually depends on the type, size, and style of bridge being built. This quick video demonstrates one popular method.

Loco Wheels Spinning
Richard has this question for readers:
“Hello, I have a Marx 999 and when applying power to the engine only the wheels spin and it doesn’t move. Is there an adjustment on the copper shoe? I can push the shoe and it springs back fine. When I give it a push it moves a little but stops and the wheels continue to spin? Thank you in advance.”
Digitrax DCS 52/Tsunami PNP8 Programing
Randy asks readers:
“I am a newbie and am confused. I have two HO scale locos which are DCC. Both have been running. Now one still runs but one does not. When power is applied the loco begins the start-up sequence sounds but nothing else. I don’t know where to start.”
NEM Couplers (Farish, Dapol) Constantly Uncoupling
Shaun models N scale and has this question for readers:
“I’m tired of my NEM couplers uncoupling and was hoping for advice as to what these could be replaced with? Or for suggestions on how to keep them coupled?”

Difficulties Coupling and Uncoupling Smaller Scale Model Trains
Tony asks:
“I have never had a go with N scale, but have done HO operations. I raise this because I’m about to go with either HO or N scale for my new layout. Yard operations is what I like doing best so I assume with N scale I can probably do more in a smaller space. My reservation is uncoupling and coupling rolling stock and whether N scale is as easy as HO, or will I encounter more problems. I just thought someone might enlighten me. Thanks in advance.”

Here’s How to Build an HO Scale, OO, or N Scale Grain Elevator For Your Model Train Layout
Why Some Model Train Layouts Are Too Predictable
The reason some model train layouts turn out better than others often comes down to realism and aesthetics. To look realistic and not “toylike,” a layout should not be too predictable in design. A mainline running close to the edge of a standard 4ft x 8ft space and then curving at the end to form an oval will look “toylike” unless there is clever scenery or props to disguise the predictable track configuration. Where possible, it usually looks more realistic to include gentle curves (just like on a real railroad) and position the mainline at a slight angle from the edge of the benchwork. Hiding the curves with tunnels or hill cuts effectively distracts the eye from the fact that the train is running around an oval.

Another alternative is to make the layout point-to-point. Real railroads work this way so why not yours? Unless your whole purpose is to run the train in a continuous loop, a point-to-point layout featuring two separate industries or towns that exchange goods is the most realistic way you can operate. Remember, though, to figure out how to turn the locomotives around at each end. A turntable, wye, or reversing loop may be necessary but they also offer additional challenges as well as interest and convenience. The available space is obviously a big factor to also consider.
Engine With Poor Smoke Output
Fred has a Vision line Big Boy and asks readers:
“I am looking for a video or info on removing the shell on my Vision Line Up Big Boy. I want to replace the smoke elements. It was sent twice to Lionel only to last for a short time. I have replaced elements on my diesel, but I am apprehensive about this large steam engine. Thanks.”

Flex Track On Module Joint OUCH!!!
Ryan shares this question:
“I know I got things wrong when I built my layout with 2ft x 4ft modules and had some flex track split on the curve. I shouldn’t have used flex track on the module joint…I know that now OUCH!! Is there a quick fix, or do I need to relay the track?”
If you can assist Ryan, please add your suggestion or comments under this post.
Is Your Track too close to the edge of the benchwork?
Space limitations may tempt you to run the track close to the edge of the benchwork. Doing so could allow for an extra track, but the big risk is that your prize loco could end up wrecked on the floor.
The accident might not be the result of an operational derailment. Instead, it might simply be because someone caught the train with their elbow, or perhaps an earthquake shook it free. When gravity comes into play the only direction is down, and the only thing stopping your loco will be the solid floor which could be several feet away.
Trains generally look longer when they disappear momentarily behind a tree, some vegetation or a structure. Where feasible, try and move the track at least 2-3 inches back from the edge of the benchwork and add some small obstacles between the track and the edge. Use some well-glued miniature bushes, a small slightly raised bank, a robust fence of some kind, or some clear acrylic plexiglass to form a physical barrier.
