If you look at the sheer population of London, it isn’t hard to fathom why commuting by car would be difficult. You also cannot deny the size of London and how hard it would be to walk from one side to the other.
The tunnel itself was build by Sir Marc Brunel and his son, Isambard. Their goal, when it opened in 1843 was to enable cargo to be transported from one area to another by going under the river Thames. However, it didn’t go as planned.
Money became an issue and ultimately the tunnel was opened as an attraction for pedestrians. Opening day caused a commotion and it is rumored that 50,000 people walked through the tunnel.
As time passed, the railway decided to put the tunnel to use in 1863. Over the following 50 years, even more tracks and tunnels were added.
These tunnels are small, the trains that travel through them must also be small. To combat the “tight” feeling, these trains are made comfortable and there are designated spaces for you to stand if you are waiting to board.
