If I have this figured out..these pictures should work. Second section finished, painted and set in place for the time being. Still have work to do on the piers, and need track down, but it will look basically the same.
I put in three photos showing where the bridge sits in my layout, the last one showing a good portion of phase one. Next spring if all goes well phase two can just maybe get done to the point of running.

Garry, very nice work. You used plexiglass. What did you use to cut it? I like the look that you were able to create with it. Do you have pictures of the bridges with track and trains running? Please, if possiible, could you give me some detailled instructions? Thank you.

Biff...............I used a table saw with a 7 inch plastic/aluminum cutting blade, it cuts cleanly and easily this way. I found it was best to do it fairly slowly so the plastic didn't get hot.



Plexy with styrene parts added on and ready for painting. Glue used was methylene chloride, which usually is sold where plexy is sold. The same glue holds the styrene to the plexy, and holds well.



Picture of first section before being installed on layout. Used Krylon camo black and camo brown to paint them.



Second type of bridge using the same system. No pictures of track down yet, got too wet to keep working on layout. When / if the weather drys out some I will get back at it.

For some reason the second picture did not display But the third Picture is a great over view.

You are going to have one beautiful looking rail road when you get done.

Your bridges and your landscaping look great. Most people put the track down befor the plants. Yours plants look pretty well established, so is this a pre existing garden or did you just decide to do the plants befor the track?

The whole layout area was grass and a vegetable garden before the railroad was planned. I designed the layout knowing where the river, mountains, tunnel and wharf area would be and also what diameter of curves there would be, before starting. Since I am hand laying my track with aluminum code 250 rail I needed a good solid base for it, so went with the concrete, so all the track placing was worked out in advance. The idea of hand laying all my track is taking longer than first figured...big surprise
....have most made up in sections like sectional track, in differing lengths, just needed the bridges built and now the weather to cooperate some. Looking forward to making some switches up and seeing how they work out. Figured I'd do the plants and moving of dirt before any track got down...less chance of dropping something where it shouldn't be dropped. So far all has gone well, slow, but well. ! Hope to have things up and running soon...but worst case would see it done by early spring. Really looking forward to seeing first run of first loop. Already have second phase of layout planned, but first things first

Hi Bills....got a problem with pics of construction...didn't take any until it was mostly together...I know, bad of me. I can tell you though that I cut out the three girders for each bridge section first...all three exactly the same size and shape. The plexy is all cut from a 1/8th inch thick sheet. After cutting out the girders I cut the two bases for each side where the track would be. These bases were then supported by a box of 1 inch strips of plexy glued to the bottom of the base, to give it more strength and more area on the sides to glue to the girders. Hope this is making sense so far! I also added another length of plexy where the track would sit so it would drain off to the sides in wet weather...I use wood ties so thought it was a good idea at the time.
After the whole bridge was glued together, I used styrene for adding all the detail structure. To make the girder flanges at the top and bottom of each beam I glued 100 X 500 mm styrene strips. The side bracing is two lengths of thin styrene the height of each girder, glued in a T shape onto the sides of the girders at even spacings apart...on mine about 2 inches apart.
Once the whole bridge was together I used Krylon Camo black to paint it and then added some camo brown for some accenting.



Different shot of bridge for better look...if it came through okay.

Gary,
A couple of questions here-
1. What are you using for ties and what are their dimensions?
2. Are you making up sections of track on the bench and then placing them on the layout?
thanks,
Dave

Dave.........I use Red Cedar for the ties.....I cut the ties to 7/16 X 7/16 X 3 1/2 inches and then soak them in used diesel oil for several days, then let them dry out for several more. I find they dry well and aren't messy to handle, but look nice and dark with the grain of the wood showing through. I'm happy with the way they look when finished.
I make jigs that I keep in the house to make the lengths of track. The straight track is made in six foot lengths, which I can cut to the lengths I need when laying it. The curves are made on another jig I made, which is laid out to lay both 11 foot dia. curves and 12 foot 3 inch dia. curves....the two sizes I am working with. I am making the curves in lengths of 2 foot, 3 foot and 5 foot, which I can also cut to any other lengths I may need. I don't like making the curves any longer than the 5 footers as they get a little more difficult to handle moving them out to the layout. I also made a thin plywood jib for the curved track that fits between the rails, it makes sure that the track is in proper dia. of curves before final fastening in place.

Regal ..........all the trees on my layout are real. Don't know the names of some of them....but there are small pine bushes...I think Black Pine ??, some Juniper bushes which I try to train to grow upwards to look like trees, some dwarf Alberta Spruce.....and several other ones that I have no idea what they are called....they just looked good so I bought them
Some are growing a little faster and getting tall too fast, so will be digging them out this spring and putting them back in pots to keep the roots in check and hopefully slow their growth. Also have some ferns and Heather here and there as well as moss and thyme. I bought some of them in little pots at Christmas, guess they were supposed to be used as table center pieces...have grown quite a lot since then. Others I bought at Home Depot, Walmart and in garden shops around my area, can never pass up a nice looking tree or shrub.

I do think at this point I have brought home enough rocks and plants to keep me happy ...........for now, and more than enough work ahead of me getting the track down and then working on phase 2, on which I hope to get the roadbed concrete poured this coming year. Great to be kept busy !!!
