    Indeed. The sudden urgency to get WA drivers who have already done the training to do coupling next week would point to this.

    The train mentioned above (117/120) did some final testing of the ASDO and PIS. All went fine so the only thing in the way now is acceptance and rostering.

    They want at least one out in the last week of Feb. But as we know its a dynamic situation.

    Yesterday 257 & 269 were parked by the underground line at Willesden Depot and another parked on the 2nd line in any ideas. Many thanks

    Provisionally put the 24th February in the diary for WA. Terms and conditions apply colours may vary subject to change in true railway fashion :D

    Sorry if this has been mentioned already (not had time to read the 72 pages) but is the 710s' replacement of the 378s the first time a London suburban radial service has been shortened (5 20m cars to 4 20m cars) with new stock in recent times?

    Were the brakes locked on?

    There are 6 dual voltage 710/2s that have 5 cars specifically for the NLL and WLL, so no. Unit Numbers 710274-279.

    The Watford DC lines have been shortened from 5 to 4 cars, so yes.

    But also boosted in frequency.

    Although I can see a need in the future to increase those 710s up to 5 coaches for Watford DC services to cope with extra growth

    But frequency's been increased from three to four per hour - so one additional carriage per hour. But that's not the full story ....

    When you look at seats and standing capacity it's less clear - partly because I haven't been able to source detailed capacity data for 710s. Can anyone enlighten further?

    Class 378 capacity:
    272 Seats (including full seats, tip up and perch seats)
    420 Maximum average load standing capacity (seated plus 25% crush)
    840 Maximum full load standing capacity (seated plus 70% crush)
    906 Theoretical crush standing capacity (seated not including perch seats) plus 7 standing customers per m2 in vestibule areas and 6 in all other )

    Four-car class 710 capacity:
    189 Seats, 489 Standing

    Eventually. As pointed out it isn’t that clear cut, but the answer to the original question, at face value, is yes. It was not a question of frequency or capacity, but purely train length.

    But the Euston - Watford route shares the fleet with the Goblin route - which would need a lot of work and creative solutions to be suitable for 5 coach trains!

    They don't all need to be converted to 5-car. There are already planned to be a mix of 4-car and 5-car 710s, so there is no reason why the number of 5-cars couldn't be increased in future if necessary.

    Indeed. Not to mention...All 710 vehicles (even the 4car AC only West Anglia ones) are numbered to allow conversion into five cars at some point in their life....with DMS2 vehicles taking on 435XX numbers despite being the 4th coach of the consist....making provision for 434XX vehicles to be an additional MS coach.

    On a side note, 121,120,119,117 all now carrying the latest software including coupling.

    This is true, but the decision was made before the additional five car units were ordered for North/West London Lines. Since the Watford 710s are dual voltage in any case, if it is seen necessary to upgrade to five cars (I believe there's six 710s allocated to the Watford?), they could now operate in a pool with the NLL/WLL units instead.

    The power supply on the DC was/is fairly rotten hence 3tph 378 to 4tph 710 only sees a net increase of 2 coaches in service (but with a mixed service at the moment so +4 coaches (and the 710 are more energy efficient somewhat helped by being ~6.2tonnes /vehicle lighter). The DNO feeder replacement has come via HS2 which allow the opportunity for substation upgrades in the future.

    Pair of 710s running down the Chingford Line currently. Didn’t catch the numbers. Guess they are testing?

    However did this happen? The service from the 1920s to the 1960s was way beyond what it currently is, with big heavyweight 6-car (some 7-car) trains every few minutes at peak times, plus the Underground running in between all the way to Watford. DC Power demand nowadays must be a fraction of what it was.

    Is Monday still the planned service entry date? If anyone has the diagrams for the 710 I would be eternally grateful

    Whilst the trains might be lighter and draw less power for moving them there are 'hotel' services on newer trains that didn't exist on older trains.

    I note that there are some unusual platform allocations shown in RTT at Enfield Town on Monday - the 1122 to Liverpool Street starts from platform 3 - does a cycle of Chingford / Cheshunt and ends platform 3 at Chingford at 1515. Maybe that is it - seems consistent

    2U37 1122 Enfield Town to London Liverpool Street
    2T48 1203 London Liverpool Street to Chingford
    2T61 1240 Chingford to London Liverpool Street
    2D34 1315 London Liverpool Street to Cheshunt
    2D33 1401 Cheshunt to London Liverpool Street
    2T70 1448 London Liverpool Street to Chingford

    This is a normal 317 diagram. So if it is it would do the whole thing. That train does

    1122 ENF - LST
    1203 LST - CHI
    1240 CHI - LST
    1315 LST - CHN
    1401 CHN - LST
    1448 LST - CHI
    1640 CHI - LST
    1715 LST - ENF
    1806 ENF - LST
    1848 LST - CHI
