Seems like all 6 diagrams operating as expected.

Been aboard 710263 today full return trip on the length of the line.
Notes: stunningly good acceleration. But still some very cautious braking.
First driver could not seem to activate the Passenger information system ( PIS). So no announcements en route. 2nd driver has activated the PIS correctly so we get announcements and visual information.
Air con is quite cold. It claims to be intelligent but obviously it is not that intelligent because I would like it's a little warmer. Sitting in a tee shirt and shirts was not a good idea despite being 27 deg C outside.
Aircon is quite loud. Other noise such as traction motors and rail/ wheelset interaction are quite low but what little you can hear of them is drowned out by the air-con. Love the large windows..gives a bright airy feel compared to the claustrophobic 387s.
Ride is quite smooth despite poor quality track in places.
Other Goblin notes: Glad to see the long standing 20mph restriction in both directions has been lifted between South Tottenham and Blackhorse Road - but annoyingly a short 20mph TSR has appeared on the westbound line further east.
Is there any scope to increase line speeds between South Tottenham and Upper Holloway? This section now feels even slower than ever. It seems straight enough to allow a modest increase in speed.
Timetabling: Westbound trains leaving Upper Holloway towards Gospel Oak should be timed to leave as the Gospel Oak to Barking service leaves the bay. This would save westbound services crawling along and sitting outside Gospel Oak waiting for the bay platform to be vacated. This doesn't seem to be an issue at the Barking end. Barking services seem to be timed to leave Woodgrange Park a short while after the Gospel Oak service has departed Barking. So unless the service that leaves barking is running late, Barking terminating services get a reasonably clear run in to the station bay platform.

Probably not until all of the 710s for the Goblin have arrived, the other routes will need their 378s back.
Now that we have a full 6 train service enforced, will the two extra "peak buster" services also be added in the form of two more 710s, or will they just stick with 6 train in ciculation while starting to replace the 378s to be reconfigered back into 5 car formation?

Barking station Jn works on minimum re-occupation so if you leave Gospel Oak earlier you’ll sit there instead. Same reason the accelerated times have just led to longer station time and not end to end.

Standard six units, absolutely no need for a peak extra with 4-cars!
Give it a bit of time and I'm sure they will fill!

could the turnaround times be reduced?

But probably not until the next timetable!

Then you’d just sit outside one end even longer. Both leaving early puts you back to where you are now?
The 4th DC service may have assumed running with a 710 rather than 378...
One short on the ELL too which is potential a bigger crowding issue, maintenance will have been a headache in the interim and all 3 units of the Goblin will be due soon. The refurb programme will want to be restarted.

Unless the missing diagram has led to a capacity crisis I suspect it may well wait until the next 710s are available before going 4tph. Unless of course they will still have the 'Reduced Service' flag up which I'm sure TfL will want gone.

Are most diagrams on the GOBLIN 710s as I want to see one on Saturday

No. Three diagrams out of six are 710s. The remainder are 378s.
At the moment it's essentially every other train (378, 710, 378, 710 etc), so it's quite easy to find one, either you wait 15 minutes or you wait 30 minutes (or even less if you can travel in either direction from an intermediate station).

Does anyone know what the power output of the 710's is? I haven't seen any information on how many axles are powered and what the rated power outputs for the traction motors are.
And are the power figures the same for AC and DC operation, or is the DC figure lower?
The consist plated maximum speed is 75mph. While the maximum speeds of 45-55mph on the majority of London Overground routes suggest this isn't an issue, one night have thought a 90mph maximum unit speed would be handy for stock transfers etc.

50% powered axles
225kW traction motors so 1800kW (4car) or 2250 kW (5 car).
The also weight less than anything made in the last few decades...

Are the traction motors in matched pairs like the 345s? (i.e. 2-Bo, Bo-2, 2-Bo, Bo-2 ?)
yes, with traction electronics on 1st and 4th cars
[Crossrail will have adjacent groups of 6TMs when the extra cars are added.]

I had a look at the running and dwell times, and it seems you could trim some of these back to create a 30 min end to end timing (say 31 mins with an extra min recovery at the end.
So an X;00 departure from Barking could end up at Gospel Oak at xx:30 with an 8 min turnaround to leave at xx:38
Assuming the Gospel Oak starter leaves at xx:23 - you would easily clear the bay platform for the incoming service eventually arriving Barking at xx:53(54) - that would leave a 6- 7 min turnaround at Barking for the xx:00.
Theis is based on a wealth of real recorded running times and assuming just a 30 second stop at each station en-route. Obviously recovery time and extended dwells could be added. But this would eat into the turn around time at each terminus. The timings also avoid conflicts at each end, but not sure they allow much time for freight to be pathed through easily enough, probably slightly less easily than now, which may be why the dwell times and running times are fairly relaxed!!
Edit: This exercise was based on timings achieved with a Class 172 diesel, so a 710 with its superior acceleration and braking could easily keep to this schedule!

Are the class 710s operating the same diagrams every day (if so could someone please post them (if it's easier I don't need full diagrams, just which departures are class 710s as I should be able to work it out) as I will be in London on Friday) or is it rather random (as in, "today we'll put one on the xx00 and xx30, but tomorrow it will be the xx15 and xx45)?

It's not random. On RTT, its those shown as STP with ID 2Gxx
The following filters will give the full list for Friday (and every day this week):

http://www.realtimetrains.co.uk/sea...6/28/0200-0159?stp=S&show=pax-calls&order=wtt
In other words:
From Gospel Oak: 08:20, 08:35, 09:05, 09:50, 10:05, 10:35 repeating every 3 hours
From Barking: 08:18, 09:03, 09:18, 09:48, 10:33, 10:48 repeating every 3 hours

4 electric trains per hour... only one year later than planned. Now when will we have 8 710s in use like we had 8 172s?

Looking at Goblin only, because the 710s will be a common pool with the DC lines, I don’t think you will ever see 8 in use, maybe until the riverside extension is finished. The peak extra short workings on the Goblin operated by 172s won’t be planned for in the EMU timetable.
