Amazing Footage Shows Record-Breaking HS2 Bridge Slide Into Place In Time-Lapse

In a huge feat of engineering, HS2, Ltd has delivered the world’s longest ‘box slide’ to move a 12,600 tonne bridge into place over the M42 in Warwickshire. It took just over 40 hours, at a speed of four metres per hour to slide the bridge into position across the motorway - seven hours ahead of schedule. HS2 and their contractors worked in partnership with National Highways to deliver this intricate operation. The bridge was built over six months on land next to the motorway. The giant 86-metrre-long structure has a base, three walls, and a top slab. The sliding mechanism was designed by specialist civil and structural engineering company Freyssinet. It allowed the box to be pushed into place over the motorway on a guiding raft over a distance of 165 metres which is believed to be the world’s longest box slide. A team of 450 people worked around the clock on this incredible operation to move the bridge into position on the M42.

All this cost and expense to save one hour on train journeys.......and you won't be able to go on them when the Train Drivers or Rail Staff are on strike

I posted this because it seems to be really clever, and I thought it would be of interest to @Tikay10.
I have never thought that the reduction in journey times could justify the massive amount of money being spent, or that the extent of them could make a real difference.
The have argued that a saving of 20 minutes on an "Up North" journey suddenly makes it worthwhile for someone to travel to take up a better job.
Surely people are prepared to get up 20 minutes earlier to take up a better job, wherever they live.
They now appear to be arguing that HS2 will provide an increased level of capacity that is badly needed.

Although the most import thing that commuters seem to require is a level of reliability which our railway companies seem unable to provide.

It is a massive amount of money to spend, and it will surely be wasted if they continue to provide the current level of service.

They also seem to be continually cutting back on the extent of it, yet the cost keeps rising.
