I use Moorgate station regularly, as there’s a Leon Restaurant just outside the station, that looked after me properly during the Covid-19 Pandemic, so when I’m in the area and need feeding I pop in.
These pictures show the four bay platforms on the Sub-Surface lines.
Note.
- The pair of platforms to the left or South are numbered 5 and 6 and used to handle Thameslink trains, that ran to Moorgate station.
- Platforms 5 and 6 used to be electrified with 25 KVAC overhead wires.
- The pair of platforms to the right or North are numbered 3 and 4 and are used to terminate some Metropolitan Line services at Moorgate station.
- Platforms 3 and 4 are electrified with London Underground four-rail electrification.
- The number for Platform 4 can clearly be seen.
This map from cartometro shows the track layout in Farringdon, Barbican and Moorgate stations.

Note.
- The multi-coloured tracks and platforms of the Metropolitan, Circle and Hammersmith & City Lines running through Platforms 1 & 2 at Farringdon, Barbican and Moorgate stations.
- The multi-coloured tracks and platforms of the Metropolitan, Circle and Hammersmith & City Lines terminating in Platforms 3 & 4 at Moorgate station.
- The purple tracks and platforms of the Elizabeth Line running underneath the Metropolitan, Circle and Hammersmith & City Lines and their stations.
- The maroon and white tracks and platforms of Thameslink running through Platforms 3 & 4 in Barbican station and terminating in Platforms 5 & 6 at Moorgate station.
- The black tracks of Thameslink running through Farringdon and City Thameslink stations.
- It would appear there used to be two junctions to allow trains from Moorgate to go North through Farringdon station or South through City Thameslink station.
- The Thameslink tracks have two useful crossovers.
- The black tracks of the City branch of the Northern Line running through Old Street, Moorgate and Bank stations.
- The black tracks of the Northern City Line running through Old Street station and terminating in Moorgate station.
- The red tracks of the Central Line running through Chancery Lane, St. Paul’s and Bank station.
Because of the layout of the various tracks new connections and improvements may be possible.
Extending The Northern City Line To Bank Station
In Walking Along Moorgate – 30th September 2020, I describe some of the possibilities opened up by the design of Moor House, which has been built to allow more tunneling underneath.
I believe two extensions South from Moorgate station would be possible.
Note.
- As the extension to Bank station has dug tunnels all over the place, I would expect that the engineers on that project would have a good idea on the best way to connect Moorgate and Bank stations.
- I usually use the Northern Line between Moorgate and Bank stations, but sometimes the Northern Line is rather crowded.
- The Northern City Line is being resignalled and may have an increased number of trains, so more passenger capacity may be needed.
- If a new station were to be built at Lothbury, it might be possible to improve step-free access to the Northern City Line.
- A new station on the Northern City Line and a pedestrian tunnel could connect to the newly-installed travelator at Bank station.
There are certainly serious possibilities to improve connections between Moorgate and Bank stations.
Could Metropolitan Line Trains Be Turned At Moorgate Station?
Currently, there are eight trains per hour (tph) between Aldgate and Uxbridge in the Off Peak.
With the new signalling on the Sub-Surface Lines would it allow more trains to operate, if some Metropolitan Line services were terminated in Platforms 3 & 4 at Moorgate station.
Would It Be Worthwhile To Run Thameslink Trains Again Into Moorgate Station?
It would only need to terminate trains from the North, as trains from the South can terminate at Black friars Station.
Perhaps a two tph service from a convenient station would suffice.

In the Wikipedia entry for City Thameslink station, there is a section called Future Proposals.
This is said.
An underground passageway linking City Thameslink to St Pauls tube station to provide an interchange between the London Underground Central line and National Rail services on the Thameslink (route) has been suggested by London TravelWatch in a report in 2014 which suggested it would benefit passengers travelling from the Central Line catchment to Gatwick and Luton Airports.
St. Paul’s tube station does not have the best access, with two sets of escalators to get to the Easttbound platform, which is underneath the Westbound one.
This picture shows the lobby at the bottom of the second set of escalators.

The Eastbound platform is through the opening on the left.
Could a tunnel to the West be built from this lobby?
This map from carto.metro.free.fr shows the layout of lines at City Thameslink and St. Paul’s.

It would appear that a pedestrian tunnel could be bored from the Western end of the platforms at St. Paul’s to connect to the Northern end of City Thameslink.
- A travelator could be included.
- It would create an accessible route into St. Paul’s station.
- Intermediate entrances could be provided to give access to important sites like the Western end of St. Paul’s cathedral.
Property development between the two stations will probably be the catalyst to get this link built.
These pictures show Paternoster Square, which lies to the North of St. Paul’s cathedral.
I wonder if provision was made for an entrance, when the area was redeveloped around twenty years ago.
It would surely be an ideal place for an intermediate step-free entrance to any pedestrian tunnel linking St. Paul’s and City Thameslink stations.
Conclusion
Done properly, it would do the following.
- Add step-free access at one of London’s most important stations for tourists.
- Create a link between Thameslink and the Central Line.
- Create a shared entrance to both stations in the Paternoster Square area.
Obviously, the figures would have to add up.
