Answered Questions

These are some the questions I’ve been asked during tours and to which I knew or subsequently found out the answer. Questions still challenging me are at Unanswered Questions.

Is St Anne’s church in Limehouse still an active church?

It is Church of England and has services on Sunday morning and evening.

Which Cannon Street building has water filled piping to help with cooling?

80 Cannon Street built by Arup in 1976. The pipes are actually are to help keep temperature down in event of a fire.

A mother protecting her child, shown as a bird’s wings wrapped around a fledgling.

Do you ever see rats on this [Limehouse and West] walk?

No.

It is not Art Nouveau. It has no particular architectural style but might be deemed “Victorian Railway Utilitarian”.

What are the logos on 1 and 5 Bank Street [Isle of Dogs]?

Why are you called Pudding Lane Tours?

In the 1970s my father worked in Lombard Street in the City. He would take friends and colleagues on walks around the City (for ‘walk’ read ‘thinly disguised pub crawl’) and several of those walks started in Pudding Lane.

What was the route of the first Docklands Light Railway line?

The network opened with two lines. One from Tower Gateway on the eastern border of the City to Island Gardens in the south of the Isle Of Dogs. The other ran from Stratford also to Island Gardens.

Why is swimming dangerous in Shadwell Basin?

Crocodiles, obviously!
One hazard is underwater obstacles. Another is silt – if a swimmer gets a foot stuck then gravity will drag them down into the mud. Three deaths by drowning have been recorded since 2010.

Would the flats around Limekiln Wharf flood if the Thames Barrier failed?

Based on some historical data and back-of-a-fag-packet reckoning, water could rise to 10 feet on top of high water on a “spring” (high) tide. This would be enough to burst the banks at Limehouse but 1st floor properties would not be directly affected.

Is Gordon Ramsey a Freemason? [in connection with his restaurant in Limehouse and the Limehouse Pyramid]

Possibly not the strangest question I’ve been asked but certainly a runner-up. There’s no reason to think so but members’ records are not accessible to the public nor indeed to other Freemasons.

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.

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.

The Tower Subway features on my Tower Hill tour.

Wapping Tunnel and Station

Wapping station opened in December 1879 as part of the East London railway but its story began over 50 years earlier.

in the early 1800s there was a need to connect the north and south docks. There were two unsuccessful attempts to dig a tunnel but these were thwarted by the soft clay and quicksand which caused the tunnel rooves to collapse. The project was declared impractical.

A French engineer, however, believed that he had a solution. Although he he no record of tunnel building he persuaded investors to finance a tunnel from Rotherhithe to Wapping. One of those investors was Arthur Wellesley, the Duke of Wellington. That engineer was called Marc Brunel who had patented a device called the tunnelling shield.

How did this work? Brunel had chanced upon a marine creature called a Shipworm. This bored tunnels through wood but in its wake secreted a coating of limestone particles on the tunnel walls to stop them collapsing.

The shield had similar principles, a round framework accommodating a dozen or so men who would dig into the sand and mud whilst bricklayers reinforced the tunnel walks behind them.

Construction started in 1825 and progress was slow, about a foot per week. There were often leaks and noxious river water would poor through. Other hazards were methane which was inflammable and hydrogen sulphide which was poisonous.

In 1827 the roof was breached and Brunel’s son, Isambard Kingdom Brunel, repaired it using a diving bell lowered from a boat. Afterwards they held a dinner party in the tunnel to celebrate!

It was finally completed in 1843 at a cost of £630,000. Instead of being a thoroughfare between the docks it was ornately decorated and accommodated London’s second shopping arcade!

The tunnel was fashionable to visit, charged an admission fee of one penny to over 2 million people each year.

In 1865 is was purchased by the East London railway and became it’s northern terminus.

It is now the deepest underground station on the Overground network.

In the 1860s a young engineer called James Greathead, inspired by Brunel’s shield, developed his own version and used this to build the second tunnel under the Thames from Tower Hill to Southwark (if you want to know more, come on my Tower Hill walk). Greathead’s shield was subsequently used to build the first tunnelled underground lines including the Waterloo & City and Northern Lines.

The Wapping Tunnel is part of my Docklands North Bank walk.
