sixoh8sixoh Posted May 8, 2011 Share Posted May 8, 2011 Gathering all the info. for the big push. Although still awaiting some drawing details from National Archives, which can't be obtained from site (closed access), only photographic details possible Hi Ron, Looking fantastic, and looking forward to the next stage of the build. I share your pain on the National Archives stuff. I requested drawings from National Archives of Scotland on the viaduct at Fort Augustus, and was told to try the council offices in Dumbarton (why on earth they'd have them I have no idea!)...

Ron Heggs Posted May 8, 2011 Author Share Posted May 8, 2011 Lovely work Ron as always. How much more can you build before you need to move into the basement? I'm really looking forward to the overall roof for some reason. Something about that screams complete madness in 1:76 and yet it is so huge! Can't wait for the next instalment. Hi, Ian In practical terms I can build everything except the station roof which as you know will be some 2200mm x 840mm. The Castlefield Viaduct is just over 4500mm but comprises 8 spans so can be built in sections between the support piers Shouldn't be too long now Cheers Ron Link to post Share on other sites More sharing options...

Hi, Thanks for your much appreciated comments At least I know they have what I want, and I have placed the order - just waiting for them to copy the drawings, etc. and post to me. They have been quite good in the past. Usually takes two weeks to get an estimate and then a further two to three weeks before they get here Cheers Ron Link to post Share on other sites More sharing options...

Southernboy Posted May 9, 2011 Share Posted May 9, 2011 As others have already said - wonderful work on the bridge - a real labour of love and really most impressive. But I'm wondering how you're going to fix the track, ballast and weather it (etc). Are parts of the bridge detachable for easy access? Or will the track be built on a slide-in-shelf or something? The answer is probably so obvious that I can't see it - and equally, apologies if you've previously explained this and I missed the post. Link to post Share on other sites More sharing options...

The answer is probably so obvious that I can't see it - and equally, apologies if you've previously explained this and I missed the post. Hi, Thanks for your comments At present the bridge sections are a tight fit but are still demountable, and will be fixed when placed in position on the layout The track base will be made from 1.5mm neoprene foam sheet to enable the track section to be slid into the bridge from the eastern end 1mm thick cork will be fixed to the neoprene to provide additional sound deadening, and then the trackwork fixed to the cork The rails will be weathered, and ballasted, and weathered again to complete the section The bridge will have been weathered separately prior to placing the track section into place I have yet to decide whether to glue the track section into place on the bridge - this could be done afterwards if necessary Cheers Ron Link to post Share on other sites More sharing options...
artizen Posted May 9, 2011 Share Posted May 9, 2011 This epic rates as one of those "How to Eat an Elephant" stories. Just Googled it and there are 78,500,000 entries!!!! My personal tastes must be different because I would build a loose plate into the track so you got that classic rumble of heavy machinery as the trains cross the bridge. Sound deadening is for whimps!!!!! It was an epic beyond my personal abilities waaaay back on page one - now you have just wound the creative screw that bit harder and raised the standard just that bit higher. Loving this thread - it will be a truly wonderful piece of madness when all the parts come together in your new railway room (or will you call it the Man Cave - get it? Man-chester Central?) I'll get my coat now. Link to post Share on other sites More sharing options...

HI, Ian Thought the latest post would tempt you back The sound deadening is going to be a bit of a trial I think - don't want it to sound like plastic nor too quiet, as you say it got to sound like a rumble SWMBO is already calling it the BRIDGE WORKSHOP, and personally taking charge of routeing the outdoor section to ensure full access to the garden Cheers Ron Link to post Share on other sites More sharing options...

Richard Posted May 10, 2011 Share Posted May 10, 2011 Ron, I have been fascinated by the work and the sheer enormity of the detail you have put into these models. In an era where laser etching and other forms of media are taking modeling to new levels you have shown that there is no substitute for actually using available off the shelf materials and building the architecture yourself. I have made several trips to Manchester in my lifetime, for football matches and for concerts at the GMEX during the 90's. I have seen the structures you are building up close. Watching it all come together is really driving me on to improve my architectural modeling as I fear it is the one area that I really need to work on. Absolutely stunning work.

Richard, Hi, Richard Your comments are much appreciated I am glad to hear that viewing my work has given you the impetus to improve your modelling, and I wish you well in your endeavours Laser etching and photo etching all have their place, but couldn't achieve the detail which I was looking to model any better, even with their higher overall costs Cheers Ron Link to post Share on other sites More sharing options...

Ron Heggs Posted May 10, 2011 Author Share Posted May 10, 2011 I wonder if anyone can help me with obtaining some photographic details of a section of the Cornbrook Viaduct which has escaped all available archives The viaduct/bridge section lies immediately adjacent to the western end of the Castlefield Viaduct and appears to be of steel/wrought iron construction Appears reasonably clearly in Google Maps Castlefield & Cornbrook Viaducts The Street Views show something of the support structures, but not clearly or in detail It is on the left and the middle track of the three, and appears light beige with grey parapets, and three overhead catenaries (Metrolink) From what I can gather it is supported on maybe four steel/wrought iron structures and one central brick built structure, and the ends are supported directly on brick built viaduct abutments Closest access is via Potato Wharf (North Side) and Blantyre Street (South Side) Any help would be much appreciated Cheers Ron Link to post Share on other sites More sharing options...

Steven It's a good job the tests will be on a span by span basis , otherwise it could be more expensive than the build You may have noticed that load tests can only be carried out before the overhead bracing beams are fixed in position because they restrict the placement of the loads Your comments are very much appreciated Ron Link to post Share on other sites More sharing options...

richard_t Posted May 11, 2011 Share Posted May 11, 2011 I've posted some images I have from a trip up to Manchester in October 2009. At the time there was no access to the viaducts via Potato Wharf due to some construction work, and views from Blantyre Street was also quite hard due to the trees. Anyhow, I've dropped 4 images: here (flashy link!) Hope they help. If you need bigger of any let me know and I can email them. Link to post Share on other sites More sharing options...

Hi, Richard Thanks for your photos, a lot of interesting detail of the MSJ&AR viaduct, and the Castlefield Viaduct at the western end as it crosses the approach road from Salford to the A57M As you have indicated the access to the Cornbrook Viaduct from either the North and South sides is a bit of a problem, and the particular section I am interested in was probably not worthy of photographic expeditions, but is really a different structure in its own right Cheers Ron Link to post Share on other sites More sharing options...
richard_t Posted May 11, 2011 Share Posted May 11, 2011 I hoped there was some detail in the background of some of the other shots, but obviously not which is a shame. Perhaps access might be better if/when the works near Potato Wharf have finished; although my work trips to Manchester have now finished. Link to post Share on other sites More sharing options...
