Bus Feed Wires

This question from a reader:

I have installed a single strand, heavier than 18 volt bus line as my feeder throughout my HO layout. Are there any advantages of disadvantages to doing this? I have as of yet not hooked the wiring up but only have slung this wire for the length of the layout.”

Rocket Jet on Model Train Display

Ted wants to add a jet model to his HO layout and seeks your advice:

“I would like to put a model of an X-15 rocket jet, like one I put together about 50 years ago, outside of a ‘Transportation Museum’ on my HO layout. All I have been able to find so far are models in 1:72 or twice that. Revell has made one that can still be found at 1/64th. I’ve found 1/200,1/100, and others more different from HO. Any ideas where I might find anything closer to HO, or ideas on how to make what’s there closer, or some way to make do. I have toyed with the idea of slightly one of the slightly smaller models somewhat in the background (much like putting N scale trains and buildings in the background to add depth.”

Will a 1/76 Tank Fit a 1/87 Flat Car?

Miles sent in this question:

“I spotted a Sherman tank I really like for an HO scale flat car load. My dilemma is; the tank is not HO or 1/87 but is more like 1/76 scale. Will this still work on my HO scale flat car?

Mixing HO with On30. A Crazy Idea or Maybe Not?

Richo poses and interesting question:

“I am thinking of running HO trains above On30 trains around the wall. Would it detract and look weird? I am thinking of maybe a dog bone design, or possibly a continuous run with a swing gate on each level to get access through the door. Not sure, so would appreciate some feedback?”

Best Type of Lightweight Ballast Material?

David has this question:

I am searching for good looking light weight ballast material for size N. I need to source enough for around 60 meters of track which I need to to ballast. I can’t have the weight of stone material is too high, as the whole layout is hanging in wires from the ceiling for elevation. Any experience shall be appreciated.”

Re-Wiring Ballasted Track

Rudy models HO and asks:

My system is all DC and my ballast is already in place. I realize only now, that I could use an 18 inch section of my layout where I could temporarily switch power, on and off, and let my 2nd engine rest, while continuing use of the first one. I already have a siding wired for this, but could use another. Is there any way to do this without ripping up my ballasted track ?”

What’s the Correct Track Spacing on Straights and Curves?

Lincoln sent in this question:

“I was wondering what is the correct spacing width between parallel straight tracks (HO), and does this differ from on curves? I presume curve spacing is different depending on the curve radius? I want to run some long freight trains and I am looking at buying some long passenger cars, so I want to have enough space between the tracks. Thanks in advance for publishing my question, and to any rail fans who can help out.”

S-Curves can Derail Trains

 

S-curves can be a railroader’s worst nightmare, yet they are a feature of many track plans because they can add interest to a layout. If you are going to add an S-curve, plan it carefully. That means that you need to have at least one straight section of track at as long as your longest car between the curves. Otherwise, regular derailments might become unwanted events on your layout. Fixing a problematic S-curve can be exceptionally hard once the track is permanently placed.

One of the most challenging placements for an S-curve is just beyond a turnout.  Avoid having a curve in the opposite direction immediately after the turnout diverges.  Follow the straight section between changes of direction practice described above.model railroad S curves

Old Style Station Lamps and Building Lights

Mark model HO scale and asks others in the hobby:

“I have just purchased building lights and old style station lamps from China. I was thinking that they would be easy to install and use. Wrong!! I think they need a capacitor added to make them work. Do they? If so, how do I find out what type to use. Many thanks.”

Will Any Decoder Do?

Ben sent in this question for readers:

“This might sound stupid but can I use any decoder model in a locos? I ask this because I will be soldering the connections regardless and know the frames can vary between manufacturers, so can I still choose any decoder, or will I need specific decoders for certain locos?
