Adding A Residential Street Scene To Your Layout

The modelbuildings.org site has a range of plans for making a residential street scene including 3D UK and USA style houses as well as a range of space saving scale model houses in low relief for positioning against your backdrop.

The feedback on these 8 scale model houses has been excellent with many readers telling their friends about them. The designer of these 8 plans certainly spent considerable time perfecting the accurate and intricate details… and it shows.

The 8 scale model house plans are available now for 70% off the individual listed price.

Verandas and posts can easily be made using balsa wood and then be painted. You can print out extra windows and doors and glue then behind cut out doors and windows to give an added 3D effect, or you can cut out 3 sides of a door or window and leave it slightly open… again adding to the 3D realism. Ground cover is obviously not included, but most in the hobby will want to do this themselves anyway.

Sudden DCC Section Power Failure 

Steven asks the following:

“I have an HO layout that is on 3 levels. Yesterday I had a derailment on a track joint in the start of a track segment where the middle level has a climbing segment to get to the upper level. Everything was fine up to that point but after the derailment the entire upper level is dead as a doornail. Prior to the joint where the derailment occurred, everything is normal.

There is no “clicking”, no flashing lights or other obvious signs on the track decoder board. I’ve pulled the plug and allowed time for an attempted system reset without success. I’ve swapped locomotives without success.

I am a complete idiot when it comes to electricity (the wiring was done for me). So forgive me for that.”

Advice on Building First Model Train Layout

Mark is starting out in N scale and asks:

“I’m new to the hobby and looking to build my first layout and it will be going in my spare room. I was wanting to run a double main line layout in two (2) different level and was going to do it in a L-shaped design. My dimensions will be 116 x 36 along one wall and 72 x 36 on the short side of the L. I have 2 questions what height of the levels is everybody using on their layouts and will 36” be too wide? Thanks for your help and opinions.”

DCC Wiring – Separate Bus Lines for Turnouts

HO railroader Dan posted this question:

“I’m new to DCC and I’m building a new layout 12’ x 12’ with 3 levels. I understand Bus Wiring and Track Feeders and how to run the feeder wires to the bus line. I will only be running 4 to 5 engines at most. I plan on using a MRC system (not sure which one yet, however wireless seems the way to go) want to put the track on the MRC system and power the turnouts on a separate system. With my DCC wiring do I need to run a separate bus line for the turn outs?”

240V 10amp Extension Cord Wire on Model Railways?

Phillip moderls OO gauge and asks:

What’ the correct wire thickness?

“I have plenty of 240V 10amp extension cords in my shed. I was therefore wondering if the wire could be used for bus wires on a OO/HO DC model railway? Or, would the wire be too thick for the power going from the controller to the track?”

1/72 Models on HO Train Track

Bob is hoping someone can help:

“I’m considering getting one of those really big 1/72 German WWII military railway gun models for the HO layout and putting it on some kind of track.

I’m thinking for a static display I could probably get by with just a few feet of track. I believe I could make the track to suit the model’s trucks using code 100 rail on plastic HO tie strips. Of course I would prefer to be able to pull the models like any other piece of rolling stock.

The only way I can see to set up the models to be pulled by a loco would be to use HO track and either modify the model’s trucks or replace them. I doubt if the model’s wheels and axles would be suitable for actually moving the model. The prospect of scratch building four or eight 5-axle or 6-axle trucks is a bit daunting.

Has anyone set up one or more of those big guns on a layout, or tried to do it? Thanks for sharing your experience.”
