If anyone has the diagrams for the extra 2 717s being introduced from next week, I'd really appreciate it if you wouldn't mind posting them, thanks.
Yeah, over on wnxx someone posted all 5 of the ones that are 717s in service so far. If you want I can copy and paste them onto here. Those diagrams are still accurate, but from next week they just wont be all of them in service. They're not going to be converting them back to 313s are they.I asked GN Twitter this morning where the 717s rosters are. They replied they've been removed due to increasing number of 717s being introduced.
Does anyone have the updated diagrams for tomorrow?
First go on a 717 today, unexpected but such is the level of disruption elsewhere, the NCL actually worked out my best route from Holborn to Liverpool Street (!)
Impressions as you might expect, like a 700 but worse. The seats are fine enough for the shorter journeys these run compared to Thameslink though the legroom intrusion is still a little frustrating.
Overall though despite the rather sorry state of the route being a bit depressing I found the units themselves a bit disappointing. Heating was set pretty high compared to the A/C on the 700 I took to Finsbury Park, the acceleration was pretty comical at over 30 seconds 0-30 and it took well over 2 minutes to change power at Drayton Park, well in excess of what 700s can achieve at Farringdon.
I appreciate the leisurely pace may be partly to do with the low speed limits on that route but I really feel they could do better. It's not as if 313 acceleration is that bad, 91s are faster pulling out of Kings Cross than that.
As far as I know 717s only have 50% of the power to weight ratio of a 700 (1200kW for 6 car rather than 3300kW for 8 car), so won't be anywhere near as speedy as that (I do know what you mean) but they should still be better than my experience today :PWhat you need is a late running train and a driver using the full capabilities of a 717. If anything like a 700 making up time you'll see what they are capable of. A bit like the DLR but up to much higher speeds. Enjoy!

Are the powered bogies rated the same though? If so, we should update the wiki page but I'm sure I remember hearing from someone that it was correct, likewise 707s are similarly underpowered compared to 700s - less an issue where third rail power is more restricted than overhead of course.cars
The 6 car 717 is only 50% the power of a 12 car 700 as it is only half the size of a 12 car 700. However the 717 power to weight ratio is exactly the same as the class 700 units. The RLU 8 car 700 has 4 power cars and 4 trailer cars. The FLU 12 car 700 has 6 power cars and 6 trailer cars. Like wise the 717 has 3 power cars and 3 trailer cars. The 717 acceleration is better (and smoother) than the 313 when the drivers get the chance to use them to their full potential. Also as mentioned, the 313 and 717 are limited to 30mph on DC in the NCL tunnel.
Or viewed the other way, 700s are overpowered compared to nearly all other EMUs, as has also been proposed before. Hasn’t an SWR driver said that 707s are more than capable for their routes?Are the powered bogies rated the same though? If so, we should update the wiki page but I'm sure I remember hearing from someone that it was correct, likewise 707s are similarly underpowered compared to 700s - less an issue where third rail power is more restricted than overhead of course.
The traction motors are 211kW but I suspect the Wikivalue quoted (from a Siemens leaflet) is the power draw based on 3rd rail DC draw which is software limited. (At the nice round 1600A, a familiar value...)Are the powered bogies rated the same though?

Has anyone got the 717 weekend diagrams?
