4" x 6' high = 2 foot in the ground - listed just above... do not know how to re-post a quote, sorry

Considering the thickness of your collumn ( about 4" , right?) I'd stay away from steel rebar. If you get mousture in the collun and the rebar starts to rust & expand, it'll destroy your collunm from the inside out.. There was a good article in Garden Railways a few years back on this.

I'd look into glass fiber. I have used glass fiber reinforced concrete for other small projects in the past. The omnidirectional nature of the loose fiber in the concrete makes for an incredibly strong mix. Some people have had "issues" with the finished project looking "fuzzy". If you have excess glass fiber poking through the surface, just burnish the surfaces with a propane torch to burn off the excess and it's fine.
Glass fiber reinforced concrete may be worth looking into.

That is becoming an impressive bridge!
It looks as long as my entire railroad... ;-(

John, did you consider instead of concrete column, making one out of metal, PVC or aluminum, and make it like a girder type? I dont have any pics, but I am sure someone has a couple, just have a base, then build something on the base. Kind of like you see bridges over rivers, concerete base, them girder system. I hope you are getting what I am trying to describe

Great railroad you got there John.

Some where I saw a comment about rebar rusting eventually and then the cement started to deteriorate. Later RJD

 

[Biblegrove RR]

Thanks for comments! Yes I stated I am not going to use rebar. I have thought of the fiberglass mat theory, thanks Dave. I have a pile of various broken bags of cement I purchase when I find it for $1 bag. I think there is some "fast drying" stuff, motar and portland cement... whatever I do, it's not final and would be easy enough to change. Just like to do it "right" the 1st time. MLS has saved me from many trial and error mistakes! In which has saved tons of time and effort for sure. i was going to use standard concrete mix but do not want the rock agrigate to show on the outside, would not be to scale ya know???? A friend that does concrete for a living said to use what he calls "grout" ??? Surely not the same as tile grout eh? I would think that would be too brittle.... is Grout another professional slang word for a certain type of concrete?

P.S. I am at a friends in Chicago right now and BOY, these people are sure proud of their little manicured 3x5 lawns! I cannot stop imagining every one of them having a loop of G guage around it!

John,

Grout comes in many forms. Google 'Sika 212 grout' for some info..

I can't help on local US products, there's bound to be something similar in your neck of the woods if you want to go down this path. Another $$ outlay though..

Cheers

Started the Trestle to Paradise Lake back in March and ALMOST finished!

Cannot wait! I am ready to start laying more roadbed so I can show SOME progress this year!

 

[Biblegrove RR]

70' of concrete roadbed poured this weekend! Looking forward to a track laying party this fall.....

Poured 10' section with mortar and it is NOT holding up - BIG nono and will surely regret it later. To fix or not? Sure would hate to move back a step but 3 steps forward may be worth it?

 

[Biblegrove RR]

Only $10 for enough vinyl cut to do 2 bridges! http://www.attitudedesigns.com/ they are awesome, did all my shirts and stuff too!

I think it's cool that the bottom picture will be visitors 1st view of the layout as they come up the driveway.

Not around the water feature, go accross it.

That is a great looking trestle.

Stopped at Lowe's in C'dale today to price some pavers (MENARDS ALWAYS CHEAPER) , don't know what I was thinkin.... upside-
Found out ALL plants and trees were 50% Off! Picked up my 1st dozen (beautiful) dwarf Alberta Spruces! $3.50 each....

Now I have to decide the perfect place to put them- This is the hardest part!

Railroad is looking great, keep up the good work and don't get yourself fired from that job......

I think he is going to need more than just one cookie. That was a bigger Disaster then I have ever done

Heck,that was worse then what ever Stan and I did together.

Maybe he should have the handle of TRAIN WRECK JOHN B.

Thanks to ALL who subscribe and reply to this thread!
My dirt guy showed up today and after 1 hour and $50 - My yard is a wreck once more!

Burn pit hole dug and a little spot to the left of the lower road bed for a siding.....

Wider spot up top line for a passing siding and a township etc.
May NOT look like much for $50 but it WAS 2 dump truck loads full and saved my back ALLOT of grief!
