How to scratch build a bridge

Hall of Fame Rob has been back in touch, this time on How to scratch build a bridge:

“Hi Al,

I have decided to scratch-build a bridge for my layout. This is something I have been thinking about for quite some time. I thought about it when I was building this part of the layout several years ago.

This will be a 3 or 4 part series since there is so much to cover and it will take a fair amount of time. The first video talks about where the new addition will be going. The second video talks about the drawing I made and how it is helping me to build the bridge itself.

Part 3 isn’t made yet so we’ll all have to wait a week or so.

I am building the bridge from styrene plastic. It is easy to work with and comes in many scale-sized structural shapes. I have been working with this material for several months now and find it is easy to build with.. remember the London Underground cable system? That was all styrene.

The picture with the plastic arch in it is me testing the placement and size of the bridge.

Thank you for all you do for us, Al.

All the best,

Rob”

A huge big thank you to Rob for sharing – I can’t wait to see how this looks on his layout.

There are so many bridge posts on the blog now, here are a few that spring to mind:

Michael’s bridge:

O scale truss bridge

John’s bridge is amazing:

Jim’s very impressive hinged bridge:

JIm’s curved trestle bridge:

And who can forget Dan’s which is just stunning:

That’s all for today folks. A big thanks to Rob for his ‘how to scratch build a bridge’ post.

Please do keep ’em coming.

And if today is the day you stop dreaming and start doing, the Beginner’s Guide is here.

Paint model train backdrop – Ed’s

Ned’s been touch with a paint model train backdrop post – he’s really gone to town on it and it looks great.

“We moved to North Idaho back in 2018 to retire and enjoy the quiet life. As part of my house design, I included a 24 x14 ft room in the basement exclusively for an O gage layout. The layout is inspired by the Milwaukee Road exchange and Hiawatha Trail railroad through Montana and North Idaho. I say inspired by to avoid the cranial obsession with attempting replicate Avery, Idaho – especially for my first layout. I picked O scale because I acquired our childhood Lionel trains a couple of decades ago. It grew from there.

The layout will be two levels. The upper level will be a trek through the mountains similar to the Hiawatha trail. By the way, the Hiawatha trail was converted to a bicycle “Trails to Rails” path a few decades ago. You can take a 15 Mile bicycle ride down through the mountains. The tunnels, starting with a 2 mile tunnel in Montana and ending in Idaho, are well maintained and includes traversing through or over 9 tunnels and 7 trestle bridges, very high trestle bridges.

The second (lower) level will be an interpretation of Avery, Idaho exchange where the Milwaukee Road railroad shifted from electric to conventional locomotives. While I will use most of the aspects of the exchange in the layout, I do not have the space or the experience to replicate what existed in Avery. Unfortunately, all of the aspects of the exchange were removed from Avery decades ago. Avery is about 50 miles from my house, a beautiful drive up the St Joe river.

I could not decide what years to represent or what season I wanted to present. So, I decided to include all seasons. The right wall of the room is winter and transitions from right to left to the left wall which is the Fall Wall. It will be an interesting journey. The tracks that appear in one or two of the photos is my test/learning track. It will eventually be incorporated in some manifestation into the full layout.

Enjoy!

-Ned”

Thanks to Ned.

I’m always reminded of Jeff’s post when it comes to painting backdrops:

Now on to Hall of Fame Dave:

“Hi Al,

well when I though that I had cured my track problems it started again further round the track, so bit the bullet and bought some new Peco track, taken up the Hornby Flexi which I show on here how poor it is for stability.

Pecp track now fitted, I am in the process of adding Mod rock to the banking and improving the scenics around that area.

Still got to do the ballasting and add the grass etc which I will show in my next video.

Regards

Dave”

A big thanks to Dave and to Ned for his Paint model train backdrop pics and narrative. Very much looking forward to an update already.

That’s all for today folks.

HO gauge track layouts

There’s quite a few HO gauge track layouts on the blog now – many of them are Dan’s.

He’s been kind enough to put together a post to answer the questions on his last post, which is here:

HO model railroad scenes.

“Al, I am going to answer some of the questions from last blog post.

This one had several wanting to see more of the layout views and some of the wiring.

The overall track diagram.

 HO scale wiring diagram

Actual track plan with locations marked. To the left and right the tracks go to the lower level and reconnect to really make a giant oval. The dashed line on the right is a run around track to turn trains behind the engine terminal. You shoud be able to follow the train through the colored track plan.



HO gauge track layouts:

Now for the “messy” part. Various panels and the wiring.

HO gauge track layouts control panel

Douglas Junction panel. There are 5 power packs running the layout. Photos in a bit. The selection of power is from rotary switches assigning power to the various blocks.

 HO scale wiring

Back of the panel. It is all color coded and really is straight forward. I was able to do each switch in about 45 minuets. One down side to wiring, you work for hours and then you can’t see progress, it is al hidden.

The terminal strips and distribution to the track.

The “Power Plant” for the layout. The Hogger power packs were around for a short time. They were expensive. I never cut corners for things that were very important. Where quality was needed I spent the money. These have lasted 35-40 years!

HO gauge track layouts control panel

The panel for the lower level. I can store 6 complete trains for staging and the two main lines run here, too. LEDs show occupancy. I have bulbs at each end of the track so it is easy to know where the train is. I use magnetic reed switches and powerful magnets on all locos and cabooses to spot the trains.

HO scale mirror for model train layout

I have a mirror on the floor for visitors to see what the wiring looks like under the layout.

A magnetic reed switch. The metal piece is the “keeper” that is under the magnet. These never fail and the magnetic reeds are sealed in a vacuum.

Enjoy,

Dan*”

A huge big thank you to Dan for adding to the HO gauge track layouts – again!

Dan’s pics reminded me of Peter’s: HO gauge layout.

That’s all for today folks.
