National Cycle Network

Look at the junction of CS6 and NCN4 at the south end of Blackfriars Bridge. Impossible to switch from one to t'other without either cycling across a pedestrian crossing or running a red light (there being no green phase for that turn)

Also NCNs are signed in miles and LCN in minutes - sometimes on the same signpost.

The gap between Tattenham Corner and Epson Downs

The height difference is 46m, and they are now about 2km apart (They used to be closer, but Epsom Downs station was moved about 500m north in 1989), so an average gradient of 1 in 40 would be needed. Steep, but not impossible with electric traction, but you would require substantial earthworks at the Tattenham Corner end, or a 2km tunnel.

There is also the small matter that the racecourse passes just 100m beyond the buffer stops at Tattenham Corner station!

Elizabeth line diagram at Farringdon

The absence of the Central Line at TCR may be because the interchange there isn't particularly easy compared with Liverpool St and Bond Street. Moreover, Crossrail passengers for the Oxford Circus area can use the Eastern exit at Bond Street station, which is in Hanover Square (or the Dean Street exit from TCR). No need to use the Central Line.

For Holborn it's probably easier to change at Kings Cross rather than double back from TCR. And for Chancery Lane and St Pauls it's quicker to walk from Farringdon.

Cheapest Gold Card season ticket

An annual season ticket from Pevensey to Pevensey Bay is currently £168.

Ryde Esplanade to St Johns Road used to be the cheapest, but is now £180.

Now that the Gold Card area has been extended into the West Midlands, there are cheaper ones. Lichfield City to Lichfield Trent Valley is £164. But that has now been undercut by Hatton to Lapworth in Warwickshire, at £160.

Invading England

There have been several armed invasions since 1066, such as those by the armies of Henry Tudor in 1485, by William of Orange in 1685, by the Jacobite army in 1745, and by the French in 1797 (the Battle of Fishguard). Only the first two of those were successful.

Closing tube stations

Closing Lambeth North is unlikely, as it would just make Waterloo even busier. Cheaper to keep it open than build a new entrance at Waterloo.

(Would the new entrance at Holborn have been needed so urgently if Aldwych was still open?)

Tube journey

TCR to Farringdon can be done by tube with only one change - at Liverpool Street - but it's a very circuitous route.
