heirflick Posted May 21, 2012 Share Posted May 21, 2012 ]on a quick trip to port sunday evening i saw this section of track and could not figure out what it was constructed like this for...why the split rails-any thoughts? [ATTACH=CONFIG]792[/ATTACH couldnt help notice how uneven the track was.. Quote Link to comment Share on other sites More sharing options...
BosKonay Posted May 21, 2012 Share Posted May 21, 2012 Looks like an expansion joint? Quote Link to comment Share on other sites More sharing options...
heirflick Posted May 21, 2012 Author Share Posted May 21, 2012 thought that, but why just on that section and nowhere else? wheres michael when you need him? Quote Link to comment Share on other sites More sharing options...
Glenderg Posted May 21, 2012 Share Posted May 21, 2012 Yip, sure is an expansion joint. I would think its there to minimise any expansion nearest the frog, so it expands in straight rail, rather than the crossover? Quote Link to comment Share on other sites More sharing options...
MOGUL Posted May 21, 2012 Share Posted May 21, 2012 I think the split rail might be to tie the sleepers together to prevent the moving as the rail expands. Maybe its uneven because points and crossings are packed by a different tamper than straight rail so will P&Cs are kept well packed while plain track will subside with time.

Garfield Posted May 21, 2012 Share Posted May 21, 2012 Yep, as the others have said it's an expansion joint. Quote Link to comment Share on other sites More sharing options...
gnri Posted May 22, 2012 Share Posted May 22, 2012 All quite correct, they are installed in Continuously Welded Rail (CWR) they allow for expansion/contraction due to heat and are often installed at the end of the run near points. If any one wants to model them Peco SL-44 They do actually work like the real ones do as I can testify!! Quote Link to comment Share on other sites More sharing options...

Flying Scotsman 4472 Posted May 22, 2012 Share Posted May 22, 2012 I have to agree with you Seamus about how uneven the track looks if that was a layout there would be derailments all over the place Quote Link to comment Share on other sites More sharing options...

It's a very low angle shot and it probably makes it look worse than it is, but there'll be no TGVs through there for a while... Quote Link to comment Share on other sites More sharing options...
