It’s a place where, when the weather is cool and the weathermen are working overtime, a crew can take a train through the night to get a train in.
They are working in the darkness of the night and working on the wrong end of the job.
And that is what the new London Underground has been trying to do with the new concrete operational stages.
They’re there for the duration of the journey and it is their job to put the trains in service at the last minute.
The trains can be on the line for up to 24 hours and, in the coldest of winter months, up to 14 days.
And it is this last-minute nature that has caused some controversy in the Underground, with the Metropolitan Opera saying they have been subjected to physical violence and the British Transport Police (BTP) saying that the system needs to be reformed to improve safety.
What is concrete operational staging?
When a train is on a track it is not a conventional train, it is a concrete box that has been made from a variety of materials, including concrete, wood, glass and steel.
For this reason the concrete boxes are very, very expensive to operate.
It is often a high-risk activity for people who are employed to do it.
So it has attracted the attention of a number of companies, such as Google, Amazon and Amazon Prime, who have been investing in building their own, more modern concrete operations.
It is hoped that these new operations will improve safety on the Tube and provide better service.
The construction of these new operating stages is being funded by the government, which has promised to give money to companies who have a concrete operations plan, and which are ready to take over the work if the Tube is shut down for good.
The BTP says it has already seen a return of the Tube to running.
But the Metropolitan Operators Association has welcomed the move saying that it is just the beginning.
“The Metropolitan Operatives Association welcomes the announcement by the Government to provide funding for new underground operating stages to be built,” said chief executive Paul Haddad.
This is not the first time the Tube has been closed in the winter.
In 2010, it was closed for more than a year due to a snowstorm, but the train operators say that now there is a real chance of opening in spring.
