1. Are there any locations on the network where trains could reverse but have never (or not in recent years) been required to do so?
2. Aside (obviously) from actual termini, do LUL trains always reverse in sidings, or do they occasionally reverse in the platform as happens sometimes on NR?

Regarding the District probably East Putney the rarest. 2. Hornchurch, Dagenham East, Barking W, East Ham W, Plaistow E, Bromley E, Embankment W, South Kensington W, Gloucester Road E to circle, Earl's Court W, Wimbledon Park E, High Street Ken E/O, West Kensington E, Ealing Common W, Gunnersbury W/D. |

Aside (obviously) from actual termini, do LUL trains always reverse in sidings, or do they occasionally reverse in the platform as happens sometimes on NR? There are many places where LUL trains can reverse in platforms rather than sidings, Heathrow T123 (okay it was originally built as a terminus), Hatton Cross, Hounslow Central, Northfields, South Harrow, Hyde Park Corner, King's Cross & Arnos Grove on the Picc for example. Of these Arnos Grove might be used most often for passenger services, of course at King's Cross passenger trains are seldom reversed E-W but the eastbound platform sees a lot of ballast trains reversing from eastbound onto the Northern via the loop. |

I asked because there seems to be fixed (as in routine) reversing points for trains during engineering work - like Piccadilly reversing east to west at Hyde Park Corner and Bakerloo reversing south to north at Paddington - leading one to suppose that crossovers between stations are few and far between.

Hornchurch, Dagenham East, Barking W, East Ham W, Plaistow E, Bromley E, Embankment W, South Kensington W, Gloucester Road E to circle, Earl's Court W, Wimbledon Park E, High Street Ken E/O, West Kensington E, Ealing Common W, Gunnersbury W/D. Dagenham East, Barking W and East Ham W have featured quite a lot in weekend engineering work over the past couple of years - as has one one you missed, Upney. West Ken E has a booked reverser first thing every weekday morning. I asked because there seems to be fixed (as in routine) reversing points for trains during engineering work - like Piccadilly reversing east to west at Hyde Park Corner and Bakerloo reversing south to north at Paddington - leading one to suppose that crossovers between stations are few and far between. On the Picc and Bakerloo they are few and far between - in fact most lines have very few reversing points in the central area. Reversal points are generally more useful towards the end of lines as that's where they're needed for service recovery when everything is running late. That being said though, the level of engineering works these days, and the number of disruptions that can require service control intervention, do mean that central area reversing points do have their uses. |

I don't know if Totteridge & Whetstone Ground Frame is still extant, but if it is then it must be the rarest #-over and not having been used for years. Royal Oak GF is surely also very rare?
Is there a facility for trains to exit Northfield Depot west end, cross over to the Eastbound and then reverse again on the EB and run through Boston Manor?

There's an unusual shutdown on the District line on the 18th/19th September:
No service Aldgate East to Dagenham East. I don't ever recall e/b-w/b reversing at Aldgate East in the past...

As soon as I read your post, my residual memory kicked in and the little voice said 'I'm pretty sure that's happened in the last couple of years.'.
Granted, though it is quite a rare occurence. ;D

On Sunday mornings (on a booked day) it appears that the 0537/0557 ex Upminsters terminate at Aldgate East to form the 0626/0646 WBs to Upminster. There also appears to be a 0616 Bromley By Bow EB starter...where does that come from?  |

Rather than Shunt as above for Aldgate E reversers, they have the galley note Pfm 1 or Ex Pfm 1. There also appears to be a 0616 Bromley By Bow EB starter...where does that come from? off Barking Sidings until it reverses at BbB. |

Not being a District Line user and never having travelled east of Barking, the early start time at the eastern end on a Sunday came as a surprise

Isn't the early morning District (east end) service for Petticoat Lane traffic?

Totteridge & Whetstone ground frame is still there with the appropriate signalling (prefix 'NT') showing an illuminatede 'A' on the signals involved.
It was used in anger when there was the landslip at Totteridge some 30 years ago but whether it could still be is another matter. Staff qualified to use it could be another issue.

I saw the illuminated 'A' last week when I was briefly up that way. I asked a driver who said it stood for 'automatic' though I was a bit dubious at that. Is it only a signalled move northbound?

An illuminated A means to treat the signal as an automatic signal, rather than a semi-automatic, for things such as procedures for passing a signal at danger.

An illuminated A means to treat the signal as an automatic signal, rather than a semi-automatic, for things such as procedures for passing a signal at danger. Basically it means the points are set and the frame is in automatic through running, the signals are working as automatic. If the signal fails but the A is still illuminated it can be treated as an automatic (the A guarantees the points) but if the points fail the illuminated A will go out and then normal semi-automatic rules must be followed. I remember a failure at Totteridge a few years ago when the release on the ground frame was knocked just a tad (by what I have no idea) which meant that even though the points were still secured manually, all the signals returned to danger and the illuminated As went out - a quick-thinking DMT was dispatched up there and found the source of the problem very rapidly. |
