Seen these two when I looked at JourneyCheck a short while ago, saw some yesterday too

21:40 Norwich to Great Yarmouth will be cancelled
This is due to a fault with the signalling system.

22:17 Great Yarmouth to Norwich due 22:50 will be cancelled.
This is due to a fault with the signalling system.

Earlier in the evening there was a trip in each direction cancelled due to a train fault, not sure if it was the same diagram though, don't know much about the Yarmouths, so can't say if it's the same diagram.


Abellio are just unlucky rather than it being their fault from what I've read and heard.

For all those people who are complaining about the signalling faults not being real and train faults, I'm sure they will be watching the MTIN figures when they come out to see if this proves their point about the so called unreliability of the trains.

Out of curiosity, what is defined as an incident? I assume this only includes those incidents that are described and attributed as train faults in their delay attribution reason, or is this completely separate?
Isn't it a technical fault causing a delay of 3 mins or more - to the trains punctuality?

20 ESR on the Cromer Line removed 10.01.20 (13m 9ch to 10m 50ch), hopefully that will speed things up a tad :)

The 2140 Nch was down to a signal lever breaking at Brundall, (the bit that attaches to the 'trigger' and frees the lever from the frame/or back into the frame)

Tsk, modern technology is so unreliable

Thank the lord looks like the bittern line may now be useable and with new stock to boot, shame we had to endure the pain to get here.

Looking at Real Time Trains and everything apart from first thing because a train had an issue at North Walsham this morning has ran fine and on time or even a bit early in some cases

It was looking to be a far more promising day on the rural services until an HGV got stuck under a bridge preventing anything going west of Bury St Edmunds.

The 755s are really taking over now as I have only seen one legacy unit when I have been at Ipswich this week. 402 went through the middle road on test.

yes they are slowly becoming ubiquitous,
I give this thread another 6 pages till we all get tired of talking about them.

Saw a 156402 and 170271 heading for Norwich off Crown Point so they are still about but I think using the 755s is probably favourable for their image.

156402 was out and about on the Lowestoft line yesterday and I had my first 755/3 trip (1545 NRW - SHM ) AND i didn't really notice any real difference in performance to the four car. Speaking of trips two didd coming off the high level seating. A warning is definitely required

The Felixstowe branch is currently suspended due to a fault with 170271. Possibly service reinstatement later.

Must be a shortage of FLIRTS though, or FLIRT trained drivers, since there should be plenty of spare units with the Lowestoft lines not operating in full and even earlier in the week it was said they had a few spare trains every day due to the number of 755s now in service.

Been a couple of issues at Norwich. Even so as you say there should be surplus. A good amount of Ipswich drivers are now trained but would need to get one down there. RR bus into the city for me today.

I finally took a ride on a 755 this morning. Only from Stowmarket to Ipswich and on diesel throughout so no rocket launch acceleration today.
One thing I did notice was that the two toilets are together in the same vehicle. Does this mean they share water and waste tanks? I can see how this would be helpful for servicing but it would also mean both would go out of service at once in a tank full/empty situation.

I've always been lead to believe a GA 360 was 1.0 m/s2. So hold on tight if a driver gives a 755 full welly from a standing start.
just done some rough calculations for mpg for the 755/3's.Please bear in mind this is by no means accurate and there's lots of assumptions in here.
Very likely slightly better for 755 as It won't be at full throttle as long as 15x to get up to line speed,or will take lower throttle setting, so duty cycle figure should reduce correspondingly.

according to deutz website the V8 gives fuel consumption of 194g/KWh, so at full whack 480KW will give a figure of 79L/h approx(or 17.4gallon/h)
multiply by 2 for extra engine (then divide by 2 for rough 50% duty cycle)- these cancel out.
now add in a typical rural diagram like norwich to sheringham- say 50miles.
this gives 2.87mpg!! shocking!!!!

compare to sprinters- i found some data for cl158(350HP/260kw) . uses 222g/KWh- 49L/H =4.63MPG
extrapolate to cl150/156(285hp/212KW) =40L/H= 5.67mpg

How many seats on a sprinter versus 755/3?
Is the duty cycle really 50%, I think it might be a bit less than that.

Er it’s a considerable amount more than that on full chat! I’m afraid your assumptions are way out.

for the power rating the fuel consumption L/Hr looks realistic enough.
50L/Hr for a class 158 would be about right,
fuel density of diesel is 0.85Kg/L

I would agree about the duty cycle though, probably is a fair bit less in the case of 755 compared to 15x, so in reality I would expect to see a number closer to 4mpg.
still quite a bump in fuel costs though, but you do get 20 extra seats(officially), and much more in standing room.

TBH I don't think we need worry ourselves over fuel consumption figures...

The 755s are here to stay, its GAs problem if they use a bit more juice, though I suppose there is an outside chance of using accurate information as part of the case for extending electrification.

oops..my bad.
just checked the formula and you're right! should be divide by fuel density, not multiply.
that gives deutz engine 111L/H or 24.25 gallon/hr.Ouch.

revised figure for sprinters 158= 67L/H or 14.76 gallon/hr
150= 55.3L/Hr or 12.20 gallon/hr

duty cycle is probably lower than I thought.
assuming diagram of 20% full load, 40% in service at 50% power, and 40% idle at 10%power , then duty cycle would be 0.44(44%)

Why is 2.87mpg shocking? I think I do pretty well to get around 90mpg average out of my plug-in hybrid, but with 4 seats that's 360mpg equivalent per seat (if they were full, but that's almost never the case, usually it's just me!), at 2.87mpg the 755/3 would have me beat with 2.87*167 = 479mpg per seat and that's before any standing passengers are considered, or the fact that some of its runtime may be on overhead wires instead...

There are 2 rows raised behind the wheelchair spaces on the left hand side when coming from the disabled toilet.
Cheers, I couldn't find the seating plan. These will probably become my seat of choice
