Damn that's a lot of concrete. It looks to me it would work just fine if they skipped every other block.

Then the track would lose lateral stability and the likelihood of it buckling in high temperatures would roughly double.

Interesting rail ties, concrete? Never seen any thing other than wood used.
Simon Ross
Simon Ross Day ago
Concrete is far more common in Europe and the UK than wood, lasts longer and is better suited for higher line speeds.

RailWAY, because this is Sweden, not America, and any translation into English should be of the British variety.
Simon Ross
Simon Ross Day ago
It should be the railway as a whole but even in Britain we think of our Railway in terms of roads, the "Up Fast Road", "Down Slow Road", etc. Even if we commonly omit the word "Road" within the industry. I can still excuse railroad/railway personally and I'm something of a pedant!

not wearing safety glasses... hard hats... or hearing protection.

Perhaps the Swedes are fools. They should wear eye pieces, but perhaps the fear of lawyers here is part of all the safety protocol that isn't always logical.

@oron61 Well I worked on a major RR for 28yrs. Track Dept. I've helped these kind of welders a lot... helping them get out all their tools, and set up for the welds.... clean up and putting everything away. Damn hard work. IMO Railroad Welders are the hardest workers. BUT... with the ATSF and BNSF … Safety gear was always enforced. Hardhats, Safety glasses, steel toe boots, boots with metal cleats when snow is present. hearing protection. all of it. No baseball caps..with no eye protection.
oron61 7 days ago
Regarding hard hats, there's nothing above their heads to fall on them or any low ceilings to hit them, so they wouldn't be needed. No loud machinery that would warrant hearing protection. And you can go buy some new eyes at your local supermarket, so who cares if a bit of molten steel gets in 'em, huh? (I agree with you there.)

So no more ratter tat tat doesn't steel expand in these very hot countries and contract in extreme cold so how does this happen now ....some videos show tracks twisted to death as there was no expansion so these would go where ? Some de rails are a coming

No because they stress the track to take seasonal temperature variations into account

i always thought you needed a space in the tracks for the metal to expand during hot temperatures.
Simon Ross
Simon Ross 9 days ago
I seem to reply to this question a lot. The track is stressed to take into account seasonal temperature variations. An extreme heat wave may still cause problems but a normal summer's day will be fine. Expansion will be nowhere near that much though under normal circumstances and 30mm is a massive gap on a fishplated joint, it should be far less, nearer the 5-10mm mark.

@bus king I wonder about extreme temperatures in UK but recently France has extreme temperatures from a Sahara desert bubble they call it . These days need to be looked at when comes to engineering. Always expect the unexpected when it comes to climate.

I asked the same question on another vid,I've seen rail joints butted tight together in summer and 30mm apart in winter(same joints) and this is in the UK(no EXTREME temps)so I'm not sure where the magic wand is but the expansion/contraction has got to be something like 1 foot per mile,obviously some clever people out there.

Here’s what I don’t understand about welding the rails...when rails are bolted together with connector plates, the rails are gapped about 12mm apart to allow for heat expansion (otherwise the rails will distort)...so what method is used to allow for expansion in welded rails?
Simon Ross
Simon Ross 26 days ago
12mm would be a wide rail gap, it's usually much smaller than that. Heat expansion is taken care of in continuous welded rail by stressing it using hydraulic tensors to local weather conditions so that it can withstand the tension in the winter and pressure in the summer. In the UK expansion joints are installed IIRC at least once every five miles on plain line and around points and crossing layouts.

Why do they weld rails today? I thought to whole point was the rails needed a gap to allow for expansion on hot days, or rails would buckle?
