Charing Cross Loop

Thanks. So that part is no more. Any idea about the East side of the loop?

What is Clive's Underground Line Guide

Thanks for the link. It will take me hours to go through that site ;D

I have the same with spotters. They know more than the staff!

And in Clive's site it says that it has been filled in with rubble!

' Clive ' mentions the problems with the Reverse Loop at Embankment "turning trains round the wrong way" Yet the loop was again installed at Kennington and is still there and in use eighty years later! :-)

To take a train from the Northern Line to Wood Lane just to go on the turntable must have been a nightmare to say the least. Did this happen regularly?

Golders Green turned Northern cars, which could get reversed on Kennington loop. Wood Lane turned Central cars, which could get reversed on Hainault loop.

Centrals did not get reversed often: services terminated at Hainault. Northerns got reversed all the time at Kennington, so there were problems for all the time that the line had handed stock. Presumably Kennington had a loop because it made reversing faster, but at the expense of operating convenience.

I think the turntable at Wood Lane was for cars that got reversed via the loop there?

Loops on Running Lines and Turntables in Depots.

The point I was making was that the use of a Loop on the running line was obviously an advantage or they wouldn't have continued to use them.
Back in 1926 Northern trains were of Standard Stock (with A and D ends)- and also for the 1938 stock and it was a simple matter to send the whole train round the loop to turn it. The turntable at the depot would only take single cars and it is difficult to call to mind when it would need to be used.
Other triangles used to turn whole trains were High Street/South Ken and the Croxley triangle. On Monday mornings some 'T' stock trains would run to Watford via Ricky. to put the train the right way round - the trains having become the wrong way round owing to the Baker St./Ricky/Watford/ Baker St. Sunday WTT having become disorganised.
The Central still has the Hainault Loop.

Turntables:

They were used largely to turn individual cars to make up a train in place of a car withdrawn for maintenance or damage. In pre-1936 built stock, individual cars were often uncoupled. On the Hampstead line, for example, Gate Stock was run as 4-car units on some trains in the peak with a motor car at each end. In the off-peak, one motor car was uncoupled to give a 3-car DM-T-CT formation. The spare motor cars used to be parked on the sidings north of Golders Green. All sorts of combinations were tried at one time or another.

Rumour has it that, during WW2 the under river section of the Charing X loop was breached by a bomb.

Well, if summat was stored there, it'd be a little bit soggy...
