Promenade - Megathread

Wouldnt be surprised if where there digging up the red concrete you will see them lift the rails too as they were laid direct on concrete while later they raised them slightly ,approx 25 mm, so will be interesting to see .

THE RED STUFF IS BEING LIFTED AGAIN?

What the actual fuck is going on down there?

And Baker's defending it? Getting proper arsey too!

Of course it's a complex project.  That was why they needed to close 3.5 miles of road for a year to get it done. Timetable after timetable has been extended by how much now?  For a 3.5 mile road?

And he's telling us it's 'part of the process'?

Sheesh.

 

Wrong coloured tarmac?

The digging of the concrete is due to a broken rail that needs replacing apparently.

How can a rail break when encapsulated in concrete and no rail traffic ?

Didn't want to be outdone by the concrete so thought it'd have a crack to?

[Two-lane]

If it has happened once, it will happen again. Pretty serious disruption just to replace a rail. Presumably if were in tarmac, someone would have swung a pickaxe to lever up the tarmac, and then laid some new matching tarmac afterwards. What's the odds that they are unable to do any colour matching if they have to do it again in a few years time.

"Regular prom watchers will have noticed the contractor digging up the red concrete in the Strathallan area. This is due to two failed welds causing a small dip in the rail track, a section of rail either side of the welds needs to be removed and replaced. In order to achieve this work the red concrete surrounding the rail needs to be broken out." according to the official propaganda newsletter

If its two welds then it would seem it is one on each leg of the track as the rail looks 40ft in length so unlikely just to be on one leg . It seems odd that two welds would fail at the same spot. I assume that they are checked by some method when complete (ultrasound?) before concreting in.

I find it hard to believe that a failed weld would cause a dip as the rail is of a big heavy section which will not easily bend and the rail there was bolted directly to the concrete so where can it dip to?.

Might be a coincidence but it was around that area that they were drilling and injecting stuff into the cracks  a few weeks ago.

The pointwork seems to have arrived as well for the track at Broadway, I hope that is not getting set in concrete.

Handy to have another expert to comment though

It is well known in Civil Engineering that if you don't get the exact shade of Red, this will cause dipping and cracking!

Maybe those key worker specialist welders weren’t quite so skilled after all.

Maybe a navvy had to do it while they were languishing in the Jurby Hilton.

Unlikely as it was one of the first bits done when they were a mere 12 weeks behind schedule.

Different rates of contraction/expansion?

With the track encapsulated in concrete these differences would cause cracking in one or the other. That's why rails laid in roads are usually encapsulated with a pliable sleeve between the rail and road

The rails in this area were bolted direct to substantial concrete base . No packing between rails and concrete unlike in the revised spec later on around Queens Prom. I dont believe this reason there giving and feel its more to do with the easiest option to deal with cracking red concrete and the packing not installed . No way those rails are dipping etc when in direct contact with a flat substantial bed .
