James Greathead

1844-1896

Born in South Africa, Greathead arrived in the UK in 1859 and studied under a noted engineer called Peter Barlow.

At this time, Marc Brunel had developed his Tunnelling Shield and used it to eventually dig the Wapping Tunnel.

Barlow created a smaller version of the shield which in turn was further adapted by Greathead to build the Tower Subway in 1870.

In 1886 a shield developed from this one was used to bore the City and South London railway (which become today’s Northern Line) and, in 1898, the Waterloo and City line – something Greathead never lived to see.

Quiz, Railways, Tangential Topics, Transport

Metro Memory

This is very trivial and tangential but it does relate to the City and Docklands and is rather fun, albeit a thief of time.

How does it work? It tests your memory or knowledge of London’s public transport.

You type in, one by one, every ‘metro’ station that you can remember. This means Underground, Overground, Docklands Light Railway and Elizabeth Line. Out of town stations such as Reading on the Lizzie Line are included (there’s a free one for you!).

Tramlink and National Rail stations are excluded unless they are metro stations as well.

A map will show which stations you’ve entered. You can move the map around to see the blanks and (maybe) remind you of stations that you have missed. The map is geographic instead of schematic and it’s interesting to see where stations are in relation to each other.

A counter will indicate what percentage of them you’ve so far managed to remember. There are over 500 in total.

Find the quiz at london.metro-memory.com – and don’t blame me if you get engrossed and forget to eat or pick up the children.

You can play it on your phone but laptop or PC is better as you get a better view of the map.

If you don’t finish in one go then you can carry on from where you left off another time. This applies even if you’ve closed your browser or restarted your computer – provided you’ve not cleared cookies in the meantime.

The game will, not unreasonably, ask for a donation from time to time. You can bypass this and carry on or bung in a few quid as the quiz would have involved quite a bit of work.

Aficionados of I’m Sorry I Haven’t A Clue will, of course, finish at Mornington Crescent.

Tower Subway

A little way north of the Uber boat station by the Tower Of London you might notice a small cylindrical building called the Hydraulic Tower,

Today it carries a water main, hence the name, but its heritage is rather different.

Quite possibly you have used the nearby Tower Hill underground station which is not far from the site of the old Tower Of London station which opened in 1882 as a terminus for the Metropolitan Railway.

Even this, though, was not the first railway on Tower Hill.

In 1870 the Tower Subway, a 2’6” narrow gauge railway, was built from Tower Hill under the Thames to Vine Lane off Tooley Street by London Bridge station. There was a single carriage which was pulled by cables connected to a static steam engine at each end. It proved unreliable and a passenger died in an accident with the lift.

In 1871 the railway was taken up and it became a pedestrian tunnel with a toll of a halfpenny. It attracted a million transits each year. A bit of maths: 480 halfpennies to the pound, divide by 52, works out at £40 per week which was not a bad bit of bunce in the late 1800s – equivalent to £4,700 in 2020.

In 1898 it went out of business because of the free crossing afforded by Tower Bridge which opened in 1894. Today it carries a water main and phone lines. You can, however, see the original entrance.

The tunnel was bored by pioneer engineer James Greathead using an adaptation of Marc Brunel’s tunnelling shield as used to build the Wapping Tunnel.
