Title: The ratio foot bridge
Post by: Matthew-peter on November 11, 2012, 05:13:17 PM
Howdy everyone,

Delfryn is in need of a footbridge and I am strongly thinking of the ratio covered footbridge, the question is, does anyone on here own one or could get the size for me, I need to know how long it is so that I can plan where abouts I shall be putting it.  I have looked online but cannee find the dimensions anywhere.

Any help much appreciated  :thumbsup:

 :hellosign: Yup! 4.75" to outside edges and 3.75" to inside of stairs.

And a bugger to build!

Thankyou very much for the info. Although you have made me nervous for the build haha.
Thanks again. :-)

By coincidence i bought one on impulse this week and have the instructions in front of me. There is a choice of making the centre span 5 or 6 panels wide, meaning either 93mm or 106mm between the columns apparently... Doesn't look too bad to build as long as you're ok with small bits and have patience... But then i haven't done it yet!

It does require patience to build !
And the spans can be cut to any length if they are too wide.

Hi  Matthew Peter,   

Did a drawing in paint  & MM  for you   ;) if it's the 222   bridge your looking at building http://www.gaugemaster.com/item_details.asp?code=RO222&style=main&strType=&Mcode=Ratio%20222 (http://www.gaugemaster.com/item_details.asp?code=RO222&style=main&strType=&Mcode=Ratio%20222)

best adhesive for plastic kits is  liquid plasticweld  dont give me any bother at all     ;)

It's these young uns, they have been metricated instead of imperialised  :D

When you add the extension piece, the bridge will span three tracks (not settrack spacing). However Ratio only provide two smoke deflector plates so you would have to make one up out of plasticard for the third track. It would be quite easy to add as many kits together for what ever span you like

As others have said not the easiest to build if you haven't got a lot of patience. Paint before you make and touch up as you go. This kit is no rush job that's for sure.

Take a look at the foot bridges on offer in white metal from p&d marsh before going plastic.

I actually found it to be quite an easy kit to build, though the roof looked a bit too thick and heavy so I removed it (chopped off the top part of the pillars late in construction).  The only parts I painted before assembly were the raised sides of the walkway (visible behind the latticework on the main span).  I expect you would have to pretty much complete the painting before attaching the roof.

Ok so I'm confused. It looks like there may be two different kits being referenced here. A concrete slab one and the (much more attractive) lattice one shown in Martink's photo (footbridge looks really great in this pic btw).

I am a bit concerned by tales of this being a challenging kit. I was planning to try and kitbash a couple of these Ratio concrete ones to produce a version with 3 staircases spanning over both a double track as well as over 4 tracks. Hmmm maybe a rethink is in order - any suggestions?

You're right - we do seem to be talking about the two different kits.  Matthew-peter's original question appears to be about the covered/lattice footbridge, which is the only one I have built.  The span here is 106mm between the pillars, or 83mm across the full-height span (using the wider 6-panel option).  The height is 22mm to the underside of the main span, or 21mm counting the smoke deflectors - this makes it suitable for platform mounting only.  I placed mine over 9" and 10.5" curves with extra-wide gaps to the platforms, so it would be quite suitable for three tracks under more normal conditions.

As for kit bashing, it has been a couple of years since I built the beast, but I wouldn't think it to be too hard.  The key is the vertical (roof-support) pillars between each lattice panel - these would keep things under control as long as you stick to an integral number of panels.  Stretching the main span could be done by joining two 5-panel floor units instead of the supplied 5+1 (though this would either need three kits or doing the floor yourself), or building it as 1+5+1 to keep it down to two kits (if a 96mm/119mm /====\ span would be enough for your four tracks), though the result might look a bit spindly.  The model is certainly robust enough, even without the roof, so there are no concerns that way.  The third stairway should also be easy, since it really just comes down to leaving off one lattice end-panel from the landing.  A final caveat - I am working from memory here, but it does sound doable.

Hi  Mike, 

My reply #5   gives dimensions /drawing for Ratio's  222 concrete footbridge asit comes for two tracks  from  just to clarify things  ;)

Oh, I see.

Laziness!  :(  ;)

As for accurate, what's a mm more or less? Nothing in everyday life!  :unimpressed:

Ah - but in N gauge a mm = 6 inches.
Size can be everything ;)

The concrete one is a model of the Southern Railway style footbridges and very easy to build. As it drops at the ends it would be fairly tricky to hack into a longer bridge though. It's a nice model.

It is in fact a different bridge to that linked, however the other day I bought a bottle of plastic weld for my wargames minis and the layout, looks like  I made the right choice haha
