Well, there was plenty of unofficial 110mph running with Class 86's in the early days - in fact most of the RPS GEML fastest times featured loco hauled speeds well in excess of 100mph.

That is a service which looks like they eventually plan to use a Hitachi 80x on - which needs slightly slower timings as it will not be as fast as a 221/390. Most likely to be run using a 390 for now and so this train will either tend to run early en route or be driven slightly slower to avoid...

From a leisure travel point of view, I find LNER prices more competitive - which affects my choice of destination by rail. It feels like DfT/GWR are trying to price us off the railway and back onto increasingly clogged roads.

Probably a better question is how many diagrams are there per day allocated for both intercity and stansted units - and how many are actually being substituted by 755 or 720 units? Based on @dk1 Reply above, there are two Norwich diagrams that would usually be allocated to 745's that now seem to...

Unless 'stepping back' occurs, it is a long walk from the front to rear cab of a double TGV set in addition to tine consumed by shutdown procedures. Then you have to boot up the computers and go through the various brake / VACMA and KVB tests etc - it does consume a lot of time - minimum 20...

To be fair, my biggest issue is the mainly hourly frequency on Sundays which does cause very full trains - not helped by the folks that sit by in a pair of seats piling their bags into the empty seat next to them - dissuading anyone else sitting there. Sunday seems to be a very busy day for...

Re dwell times, most of the mainline stations on the PLM seemed to have multiple platforms allowing 2 or 3 trains travelling in the same direction to enter the station within a few minutes of one another while allowing close headways. I recall being on a Marseille to Calais sleeper being...

Wasn't LN1 built primarily to provide extra capacity and speed on the original PLM route due to the extortionate costs vs benefits of upgrading and quadrupling the original route - in particular the two track tunnel sections? I recall LN3 being planned ahead of LN2 but delays to agreeing the...

I found that TPE 802's on their 940hp setting easily matched 2+9 HST performance on that stretch. More responsive and accurate braking seemed to offset slightly slower acceleration

Which services are they booked for? M to F, S, SU. Surely all the coupling / uncoupling needs to be planned?

Just wondering whether the 755s would be better diagrammed on the services that end up sat at Orient Way all day between the peaks?

Engine speed is related to the amount of electrical power available from the alternator to the motors. Lower engine speed equals lower alternator speed equals low power -high engine speed equals high alternator speed equals high power. As I understand it the computers controlling the traction...

Yes - torque flucatuations at those horsepower / torque levels can be catastrophic. But here is the question. After five years experience of running at higher power levels than planned for due to the curtailed electrification - why has the expected wear profile not been refined to allow for the...

Yes the London to xxxx times are quicker, thanks to the better electric performance. Not sure about times between stations on the diesel sections though. 1687701010 Here is an explanation from another driver (as explained on another forum) about the torque surge issue. "the Power Brake...

what I recall from past conversations is that the acceleration curve has been tuned to provide this initial burst of acceleration - good for exiting platforms and allowing faster platform reoccupation - but then in the mid-range the power load has had to be detuned to improve reliability -...

The GEML services to Southend, Braintree, Clacton, Colchester and Ipswich are running to Class 321 timings. That means the XX;00 Norwich service catches up the Southend service by Shenfield, the Braintree service at Witham, and then is on the coat tails of the Colchester Town service from Marks...

You would hope it is a more advanced version of the engines used on Class 80x. The difference is that EMR class 810's will have 4 GU's, but how often will this even more powerful version of the 800 series trains be running with a GU out? EDIT: To put the matter into perspective, the ideal...

They are not 100% reliable at the lower power setting either. Services will require slower timings between stations on higher speed sections of diesel running. Seems like a serious upgrade or redesign of the GU needed in the long term to address these issues - unless the failure rate is within...

Availability of 745's should be okay. GA are still running fewer Stansted services than before and fewer Intercity services. Also there are no Norwich in 90 trains either. On weekdays there are quite a few 745's parked up at Orient way between the peaks. So no perceived shortage of units...
