I am well under way with building the new rail bridge spanning the Cam River.

Will start off with the rail bridge first, called Cam River Bridge,
and build the road deck later beside the rail bridge.

I am basing the rail bridge on the Crimean Bridge in Russia.

The road bridge wont have the top arch,
small arch underneath the bridge, road deck be higher,

Deciding weather to have 4-lanes, with emergency lanes,
so people can look over and watch the trains go by.





The arch be built with two 12mm ply joined together,
couldn't make the arch one full arch, so I joined up three pieces to make the arch.

The main beam be in three pieces as well, because I can't get timber 14 feet in length.

Main beam with be joined together with two pieces, as in the bridge plan,
sides being 2 and a half inches high.










I am waiting for my brother to bring his better jig-saw so I can cut the arches to size.

The curves decking, has come form my old spiral, not usrd in the new layout.

Tried to get an 8 foot curved arch out of the 6 foot curves, didn't work using what I have.





The two straight pieces at each end, be 2 foot long, cut to shape once the arches are cut.





I like the way the stairs are on the real bridge,
will do the same, only needing one set of hand rails.

Yep planning a jumping area at the top of the bridge, for glider and power-glides.

Wednesday be our hottest day, 36 degrees and afternoon storm.

Have sorted out the garden shed, to make more work space,
can fit two modules now, Wow.





Still an issue with water coming in at the side where the bridges are,
will reseal tomorrow in the morning.

Be test storm predicted in the afternoon, Wednesday, hot day 36 degrees.
Hot today, is 34 degrees, feels like 36, was 32 degrees at 9 am when we got out of bed.

There be a second beam going in as well as in the real bridge,
height of arch being 3 feet from rail deck.


Si.

Do you have that pic. of the bloke jumping off the French cable stay bridge ?  Funny pic.

I have being sorting out my pic. folders, deleting some, may model that, ha, ha.  :)  :)

Thanks Si.

I will save the pic, a question to ask,
what happened to my Ro-Ro ship in 1:87 scale thread, and the bridge thread,
from time time, do threads get cleaned out if not in use..

Will start a new thread on the Ro-Ro ship build,
actually started work again after 12 weeks,
got one more bulkhead to cut out on the stern section.


Hi Peter.

We had a storm earlier on tonight, will check the shed tomorrow morning
I had to reseal one side, fingers crossed the shed is dry.

Can't wait till mid March, so I can start work on the new layout,
was a stinker of a day today, was 36 but felt it was 40 degrees,
same again tomorrow.

Cooler weekend coming of,
can't do anything helping my train club having a sausage  sizzle,
make a start on the bridge Sunday and mark out the arches ready to be cut.

How is the bush fires going in Victoria ?
Don't hear much now.

We had wild weather copped 220 mm's of rain in a few days

Hi Si.  :wave:

Will take your advice with starting the newest bridge Thread, will do the same with the ship Thread,
yeah sure have a few going, the 737 train-load, and the wind turbine-blade Thread.

Cooler weather coming in Saturday, sadly can't start on the bridge, will Sunday.
I have to cut the second ply layer same size, Sunday.


Peter

Success with the second sealing of one side of the shed and weatherstrips on the doors,
we had a bad storm 25 mm's in half an hour shed was bone dry.

Gee it cost a fair bit $200 all up,
had enough rain side of the house is very soggy at the gate, grass not growing.

Good to hear you have stopped the water and our fires are under control as of today.

Looking forward to see how your bridge works out and indeed the layout in the yard.

Thanks Peter

Are parts of Victoria still burning but under control ?

Yeah was on a high when I opened the shed door, to see it bone dry at long last.


Yeah can't wait to start work on the new bridge to see it come together.

Not sure what colour I will paint it, light or dark gray.

Hi all

Hope everyone is ok, been a while since my last update.

The new bridge design is coming along nicely,
I have cut the main arch sections and joined them together,
a lot of sanding to do once the bridge is finished.

Friday I marked the arch ends ready to be cut out, hopefully today,
not sure because it is very windy and cold here, can't win.

I wont cut in the wind, have a new jig-saw, and will take a while to get used to,
has more grunt than my old electric one had, no more leads to get in the way.





The first two pics of different angles,
taken of the main arch standing up, very happy indeed.

Should be a pretty strong arch when temperamentally screwed together.
I have to measure each half of the arch to be 6 foot in length, making them 12 feet.










The third pic, a side drawing of the end section of the arch.





Forth and fifth pic of the arch with the end sections,
luckily I set up a mock-up because the angle of the end section wasn't as steep.

I hope to get the four end sections on one piece,
the only way to do that is not have the side beam as long,
cutting the length back to two feet. 

I will wait till it starts to warm up, and get the two off-cut ply out,
and draw the end sections to see if I can.
Want the other piece for straight sections if I need them.

Have shifted the spiral to make the single track longer, same with the reverse loops,
they need to be long enough to fit the length of my trains,
most blocks are 30 feet long.










Final pic of the end full size scale drawing of the arch, 2 foot from rail deck.

Si. do you think that bloke be able to parachute from the top of my bridge,  :moose:  :) 
4 foot height from water line, no idea how high in 1.1 scale.

Hi Tony  :wave:


I guess that would depend on if it was a suicide attempt  :w:... or a base-jump !  :us:

Perhaps flippers & a snorkel, might be a better option, rather than a parachute !  :shocked:

Or maybe a hang-glider ?  ???


The French 'Millau Viaduct' is rather a great opportunity for 'human bird brains' !  ;)

I'd love to jump off it myself ...  :thumb:

... the French cows down bellow, are really sick of having idiots land on them, so I hear !  :P

Hi Si.  :wave:

Starting to warm up now, cooling down here,
don't know what it be like at the new house if we will have a cooler winter,
not sure about frost, will find out.





I found this pic again from one of my older posts,
what I am thinking of getting, Bosch sell them,
not sure what you call them, cross between a parachute and hang glider.

No more progress on the the bridge,
will Saturday finish off cutting the cross beams,
and start drilling them in place, then cut the arch ends.

Have being busy buying more plants that can handle the full sun,
and big job coming up shifting gravel to the side of the house, not far,
will look awesome, no mowing.

At long last the arch is finely screwed in place,
and is stopping the bridge from sagging in the middle.

I made a special centre jig, so the arch can be clamped to the jig.

I am on a big high after four different design attempts this design is working well,
and looks good when the arch hangers are drilled and screwed.

Having a break from the bridge and concentrating on the station modules,
next job, nailing down the new track, from the new track plan.

Back to the bridge to modify the piers and level the bridge,
then be able to work out the  module leg heights.





The second pic I be modelling and pulling off,
and yes I have the two locos and the passenger cars, with the boat ramp.










Last pic looking down the bridge,
every 12" foot will have a support beam working up to the top of the arch.

Plan to have steps and hand rails on the edge of the arch, probably only one side,
and a platform up to the top of the arch, for hand gliders to jump off.

Being a while from last update.
Wow, the bridge looks like a bridge now.

Today I drilled and screwed in place 6 arch hangers,
very happy indeed, the arch worked.

I unscrewed the centre arch support,
need to buy 6 more 9.5 mm round dowels to finish the arch hangers.

A lot of work to clean up the arch, got some filling to do as well,
she is going to look stunning sitting out on the layout.

Painting a gray finish.















When I screwed the other side hanger in place,
the actual arch moved into the centre of the bridge.

I found the drilling was quite easy,
that will probably change when I move further down the arch.

Have to wait till Thursday to buy more dowel,
then I will do the filling, sanding and painting,
last of all the track layout and bus wiring.

Where the saw horses are, is where the piers will be,
that's the next job, razing height 5 inches, to 2 foot clearance under the bridge.

Slowly getting there,
in the meantime will start nailing track down on the modules.

Latest bridge update.

Wow, at long last the bridge construction is finished.

Been at it for a couple of years, and on a big high,
the arch is actually working.

Next is to sand the top of the arch square,
and start painting ready to lay the track down.










The main span is 14 feet,
where the saw horses are is where the piers will go,
will have a 2 foot water line clearance.

Later will build the road bridge, once the trains are up and running,
if all goes well before Christmas.

The arch is 2 foot off the rail deck,
and will have a walkway up to the top, on the side of the arch,
only needing one set of hand rails.

My layout is coming along, have joined up two modules already,
starting the next on Friday.

Hi Peter,

Good to hear from you.

Yeah I have 3801 Lima pulls well,
if I have a long passenger train, I use a helper diesel 4222 Class same make.

Will sand the top of the arch square and underneath the arch,
so I can paint the bridge ready to nail the track down.

Hi Tony  :wave:


Your bridge is looking TOTALLY AWESOME dude !  :thumb:

GREAT photography of the work, in excellent light as well.  :s:





It has taken quite a while & quite a few 'experiments' along the way ...

... but the result looks every bit a total winner !  :bg:

Hi Si.  :wave:

Many thanks.


Yeah long time coming indeed.
 
After tomorrow the bridge be painted,
will see if I get time to lay the track down.

On a high.


The top of the arch from water line is 4 feet in height.

Later will ad the steps on the arch,
and platform on the top for hang-gliders to jump  off.

Even a nude hang glider ha, ha.  :bg: :bg: :bg: :bg: :bg:

Hi Si.  :wave:  :P  :P 

Yeah I love the cable stay bridge design as well.

The Forth bridge off the list and the Sydney Harbour bridge,
too much work, till I came up with my design,
got some great ideas to save more work and money.


Most above arch bridges are of a tube construction,
so why not have the steps inside the arch,
and a platform at the bottom of the arch and the same on top.

Will have a viewing platform at the top of the arch,
and extended platform ramp for glider jumping off.










The bridge isn't too bad,
hard to pick up, on my own more awkward,
am thinking of making a trolley to move it around with ease.

Next job to modify the two piers to gain an extra 5" inches,
from 19" to 2' feet underneath clearance.


Won't be doing any more work on the layout till early November,
and that will depend on how hot the days are.


We are in election mode in QLD.
 
I will be helping out on per-poll voting,
for the next two weeks till election day 31st.

Morning Peter

Early days, but going by yesterday at pre-poll,
our ALP candidate will get back in.

I will send you a couple of pics. of our set up with the gazebo,
was a great day, full on day again today, day off tomorrow.


I didn't get a chance to nail the track down on the bridge on Sunday, was visiting day.
Saturday I have to mow the grass, will do the track nailing after that.

Will do a photo shoot with 3801 sitting on the track, may even get out the Flying Scot,
mine has a double tender, and the second one is powered as well.

Hi Tony  :wave:


I think in the end, what works really well, is keeping the bridge ^^ MINIMAL.  L:
That is essentially 'the look' of most mooodern bridges I guess. :brill:


They have pretty much all been pared down, to just engineered-concrete & steel-string !  :P

No more pesky RIVETS these days !  :f:


All that 'Sydney Harbour' & 'Firth Of Forth' RIVETing ...

... was just TOO MANY holes to drill !!  ;)



- - - - - - -



" Will have a viewing platform at the top of the arch,
and extended platform ramp for glider jumping off."

If You Haven't Got A Hang-Glider Handy ...  :doh:


I have to say Tony ...

... I'm not convinced I wanna see ANYTHING at the top of your arch.  :us:


It just looks too darn good as it is ...  :thumb:

... & will look even better with that 'Flying Scotsman' on it !


I had a slightly clunky old 'Tri-ang' OO one about 40 years ago ...  :old dude:

... my 'Tri-ang' hoard is supposed to be limited to 'Transcontinental' HO these days ...

... Aussie 'versions' included of course !  :cool:  ;)

Hi Si.  :wave:

Many thanks.
 

Will have to wait a little while for the viewing platform,
I won't be having any steps on the arch,
as you say, the modern bridges use hollow steel beams, even for arch bridges.

I will make out the steps be inside the arch beams,
will have an entrance platform at the track deck level, and at the top of the arch.

The bridge has being painted gray, looking damn good,
very happy with the construction, and it works.


WOW  here are two pics. to blow you away.










Ready to nail the double track down and solder in the feeder wires to the bus wires,
already posted those pics, don't know why I put on an older pic.

I have decided to add in a spiral to make a longer single line running,
sadly the second level is 6 foot across,
want to make use of all the decking which is from the last module layout.

When finished will have three lots of single track running on the main line,
freight trains won't be running through the station platforms,
very happy indeed.

At long last the bridge is finished ready for the first train.

Test run my two latest trains, one a Bachman EMU 4 car set,
and a 66 Class diesel loco, my first British diesel.

Don't have the dual tender drive Flying Scot any more, or the 11 maroon coaches,
did well in the swap.





All that needs doing is the bus wiring,
will do that on a cooler afternoon, very humid here and cloudy.

I am on a big high.

Will work on the platform at the bottom of the arch and up on top of the arch,
saving all those steps and handrails, only need on the entrance inside the arch.
