First Look Inside £2.2bn Silvertown Tunnel
The title of this post, is the same as that of this article on the BBC.
These are the first five paragraphs.
For the first time, Transport for London has invited journalists inside what is one of the most controversial infrastructure projects in the capital.
The Silvertown Tunnel is 1.4km (just under one mile) long and stretches from Silvertown in Newham to the Greenwich Peninsula.
Inside the tunnel, it is extremely wide. A lot bigger than other tunnels like the supersewer or Crossrail. Boring was finished a few weeks ago.
Transport for London (TfL) says the scheme will address queues at the Blackwall Tunnel and reduce pollution. But it has faced fierce opposition from those who think it will do the total opposite and increase pollution and congestion.
And the big question is – even with mitigation – can a road tunnel ever be green?
Note.
- There is a good picture, showing the width of the tunnel.
- It is very wide and can’t be much narrower than the four-lane Queensway Tunnel, which was opened under Mersey in 1934.
These are my thoughts.
I Am Against The Tunnel Being Built
My main reason I am against the Silvertown Tunnel is that Transport for London’s mathematical modelling of and rerouting of buses past my house has been some of the worst I’ve seen. I talk about the bus problems I now have in Is The Nightmare On The Buses Going To Get Worse?
So until the two tunnels; Blackwall and Silvertown are complete and open with tolling, I won’t trust any of Transport for London’s pronouncements.
I also feel that as the Silvertown Tunnel will allow trucks to pass though, there will be times, when they will cut through the East End to get to the Motorways going North.
But now, it’s more or less finished, we will probably need to use it.
How Is The Tunnel Being Paid For?
The Wikipedia entry for the Silvertown Tunnel has a section called Costs, where this is said.
In 2012, the cost was stated to be £600m. A consultation in 2015 stated that the cost of construction was estimated to be £1bn. In March 2020, the cost was increased again, to £1.2 billion. Operation, maintenance and financial costs of the tunnel over 25 years is expected to cost another £1bn.
The £2.2 billion will be repaid by tolls on both tunnels. Effectively, it’s a Private Finance Initiative or PFI.
Can A Road Tunnel Ever Be Green?
This is the question the BBC asked in the last paragraph of my extract.
Although, I am very much against this tunnel, I do believe this tunnel can be green.
- Suppose, the tunnels were made free for zero-carbon vehicles, that were powered by batteries, hydrogen or possibly ammonia.
- This might nudge vehicle owners and operations to go zero-carbon.
This extra number of zero-carbon vehicles would help to clean up London’s air.
I wonder which will be the preferred route for trucks associated with construction to go to and from sites in Central London?
- These trucks are major polluters in Central London.
- There are sensible moves to make construction sites zero-carbon.
If the Silvertown Tunnel didn’t have tolls for zero-carbon trucks, then surely this would nudge, this sizeable group of trucks to go zero-carbon to the benefit of everyone in Central London.
The only problem with making zero-carbon vehicles toll-free, is that it probably ruins the finances of the tunnels, from the point of view of the investors.
Conclusion
I can see lots of conflict starting over the operation of this tunnel.
Woking: Train Derailed On 90mph Line After Hitting Object On Track
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Disruption has hit a rail operator’s entire network after a train hit an object on a 90mph track in Surrey.
These three paragraphs describe the derailment.
The incident initially closed four tracks between Woking and Surbiton before disruption spread across the South Western Railway (SWR) network.
Network Rail said the train hit the object at about 05:50 GMT in a 90mph area near Walton-on-Thames in Surrey.
SWR said services were impacted between London, Exeter St David’s, Portsmouth Harbour and Weymouth.
It appears that no-one was hurt.
But derailments like this have happened before.
This article from The Mail is entitled Furness Passengers Able To Walk Away From Major Rail Accident.
These paragraphs detail the story.
Furness rail passengers were woken from their slumbers 50 years ago as the carriages of an express train heading for Barrow came off the rails at 80mph.
Half-dressed and dazed sleeper-car travellers from London were led to safety up a grass embankment near Warrington in 1967.
Amazingly, not one of the passengers was killed or badly injured in what could easily have been a major disaster
The Mail on Friday, September 15, in 1967 noted: “Furness and West Cumberland passengers hung on for their lives when 11 coaches of the London-Barrow express hurtled off the rails at 80mph near Warrington today.
“The coaches bounced and zig-zagged for nearly a quarter of a mile, tearing up the permanent way and completely blocking the main London-Glasgow line.
“Miraculously, only one of the 60 passengers, who included many people from Furness and West Cumberland, was injured.
“He was Rohan Kanhai, the West Indian test cricketer, who was on his way to Blackpool.
“He was taken to Warrington Infirmary with an arm injury. After receiving treatment he was allowed to continue his journey.
I remember the story for two reasons.
- Obviously, because a well-known sportsman was involved.
- But also because British Rail put the low injuries down to new couplings between the coaches, which kept the train together.
Could it be that over fifty years after the Warrington derailment, no injuries occurred because the improved design of the train kept it all in one piece and most of the damage was to the infrastructure?
