dbcrabb Posted October 10, 2012 Share Posted October 10, 2012 That foundation is similar to the one I mentioned so maybe not so unusual after all. Founds will change depending on the site but a company called FLI structures did a lot of the masts and they specialise in screw piles thus this foundation takes the form of a grillage I think, that can be bolted directly piles or anchored into pile caps as I think that the posted picture shows. Mast sizes and styles also vary from site to site and also during your project if your unlucky ... Compound styles also vary with some sites inside self contained compound and some just trackside. Building it in a peat bog makes the founds quite large :-) Regards DC 1 Link to post Share on other sites More sharing options...
RMweb Gold Revolution Ben Posted October 10, 2012 RMweb Gold Share Posted October 10, 2012 Hello there We have one on Horseley Fields, our club N Gauge layout. This is it before installation: The mast is a cheap paintbrush shaft (to get the taper) sanded to give the eight "flat" sides; the building is scratchbuilt from plasticard, the steel base struts are just Evergreen strip and the radio "gear" at the top of the mast is just bits and bobs from the scrap-box. The cooling unit pods on the cabin were air-conditioning parts removed from a Japanese bus models. All was painted with Halford's primer grey before some parts were given a dusting of silver to represent galvanised metal. All the dimensions were guestimated from photographs; it may well be that some are not quite right, but it looks OK set in the scene! Unfortunately on its first outing at the Hoddesdon show it got a bit of a knock, but it's now been straightened up!! cheers Ben A. 7 Link to post Share on other sites More sharing options...

RMweb Premium Reorte Posted April 25, 2016 RMweb Premium Share Posted April 25, 2016 For a bit of variety I've seen them painted brown, and at least one (at Horton in Ribblesdale) where the building is stone (or possibly the standard one with a stone shell built around it, I've no way of knowing). 1 Link to post Share on other sites More sharing options...

RMweb Premium Reorte Posted April 25, 2016 RMweb Premium Share Posted April 25, 2016 I've seen them painted green, they actually stand out more! I can imagine, I think that the brown works better for that purpose. The defauly grey just makes things look temporary and messy. Link to post Share on other sites More sharing options...

RMweb Gold rodent279 Posted January 7, 2018 RMweb Gold Share Posted January 7, 2018 They are all pretty standard poles and lattice towers used throughout the mobile comms industry. I have planned dozens of these, though not for NR. Some don't have REB's, they will use outdoor cabinets where space doesn't permit. I'm not sure exactly what planning rules NR can work to, but you need planning permission for any installation, but if the pole is under 14m, you don't need full planning, you can use Licence Notification.

Unfortunately on its first outing at the Hoddesdon show it got a bit of a knock, but it's now been straightened up!! GSRM mast.jpg cheers Ben A. That has happened in real life, more than once! As for dimensions, a typical pole will be between 10 & 22m tall, carry between 3 & 6 antennas, unless it's on a headframe, in which case it could have up to 12. There will either be a cabin around 3m X 4m, or several cabinets near the base housing the BTS kit. Antennas are typically 1.2-1.8m long and around 0.25m wide, depending on the frequency band width and number of ports. Much above 22m, lattice towers tend to be used, due to wind loading. 1 Link to post Share on other sites More sharing options...

I posted a link to the legislation earlier in this thread - as the mast is "Development by railway undertakers on their operational land, required in connection with the movement of traffic by rail" then it is a "permitted development" and does not require any planning permission from the local council - it is distinctly different from the rules relating to O2, Vodaphone etc. Edited January 7, 2018 by Butler Henderson Link to post Share on other sites More sharing options...

RMweb Gold rodent279 Posted January 9, 2018 RMweb Gold Share Posted January 9, 2018 Neither are electricity pylons etc. Considering how many there are, they are under-represented. 1 1 Link to post Share on other sites More sharing options...
RMweb Premium Reorte Posted January 9, 2018 RMweb Premium Share Posted January 9, 2018 Neither are electricity pylons etc. Considering how many there are, they are under-represented. They'd be huge! A bit of Googling suggests 50m as a typical height, so that's a bit higher than 2 Mk 3s end on end. You'd need a pretty huge layout for them to not completely dominate it (and where will the wires go?) Even full-sized trees aren't that common on layouts. 2 Link to post Share on other sites More sharing options...
RMweb Gold rodent279 Posted January 9, 2018 RMweb Gold Share Posted January 9, 2018 (edited) I wonder if anyone has been brave enough to try? There's also some pretty big mobile phone installations. The one at Sutton Coldfield is/was pretty huge, ISTR it got burnt down a few years back, and collapsed. Then there's Emley Moor, all 200m or so of it. Of course, the RAN antennas are rarely that high, they'd be in the 50m bracket or thereabouts. I don't think Emley Moor is near a railway, but Sutton Coldfield can't be far. Did anyone ever attempt to include the former BT earth station at Rugby? Edited January 9, 2018 by rodent279 Link to post Share on other sites More sharing options...
