Transport for Wales 769's

[6Gtraincrew]

I'm not sure which TFW 769 unit it was but one was provided for training runs today.

According to genius, 006 was out first thing and 007 was out this afternoon.

 

[Senna1210]

007 had a

Does anybody know the nature of the problems that are causing the failures? (preferably facts and not speculation )

Thanks

007 had a door interlock issue ,006 had fuel quality issues

Looks like a possible 769 move tonight to Rhymney 5Z51 2205 Cardiff Canton Sidings to Rhymney Siding if so it’s the first time it’s run on a Saturday but looks like it’s had issues and had to reverse at Caerphilly back to Canton.

769006 had issues again

What sort of issues, if you know and can say? Related to the conversion and traction or some more ordinary stuff?

Fuel problems ive heard

Since the introduction of the new timetable in December I don't think the 769's have run a service. 003 was due to run the service this morning. Does anyone know what services they are on please. Before timetable change this ran the 2F08, 2R09, 2F12, 2R12.

 

[Jamesrob637]

They ran on the week commencing 14th of December but not sure if any have operated since. So only a few days since the timetable change.

Yes your right I forgot about that week, from my notes it seems 006 on the passenger runs and 007 on training.

003 is out from 1002 (2P10) and should remain in service departing Rhymney southbound every 3 hrs and Penarth Northbound every 3 hrs from 1133

Cheers thank you, yes I just saw it pass the house. I'm just trying to work out how it gets back to Rhymney. If it stays on service all day it's last run is the 2P19 terminating at Central then ECS into Canton. Does it then run ECS to Rhymney or does it terminate off the previous service the 2R17.

If it went back to Rhymney every night it would run out of fuel

Yes thanks Philipe, they have to fuel up. With the new timetable just trying to work out paths they are using, unless they swap with the training unit.

At the moment they would probably be working ad hoc depending on availability. 2P19 can't go through to Penarth due to Engineering work.

It goes to Canton for Fuel off 2P19 then comes back out for 2142 Cardiff - Rhymney. Likely to be doing this all week

Fab thanks for the info.

Heard a 769 failed today in between Queen St and Lisvane on the way up to Rhymney. Not sure of unit number or exact location. Power problems it seems.

769006 on 5Z45 which was a positioning move from Canton to Rhymney. Returned to Canton

Have a report from my partner that there is a 769 out today on 2R08 08:33 Penarth-Rhymney (sorry, she didn't take the number!).

It has been a 769 on most days recently. There is a regular diagram for it between Rhymney and Penarth all day. Post #1275 gives an insight into it

769003. It’s been trundling up and down the Rhymney valley all week and is planned to keep going for the foreseeable.

 

[Optom1]

003 has been out all week.A general observation,I thought was probably due to the relative silence of the units,is that they seem a little slower off the mark than 150’s.From a vantage point near Lisvane station it is possible to compare 769/150 leaving Lisvane and entering Caerphilly tunnel .For the 1/2 mile or so the 150’s are taking about 65 secs and the 769’s taking 80 secs.

So, on those timings, the 769 is taking about 23% longer than the 150 to cover that half mile from a standing start!

Not great, considering Porterbrook marketed the 769 on the claim that it would have similar performance to a 150.

 

[Optom1]

As the top speed of a 769 is 100 mph,maybe mid range performance is better,Covid prevents on train analysis.

From the footage I've seen, a 769 wouldn't have the power to reach 100mph, wouldn't get close unless going downhill.

not to mention no stretch of the line is 100 mph

They keep to the timetable quite nicely. Once they get to 15mph they go really well

 

[Energy]

They have 25 less horsepower than a 150 per car (50hp less for a 4 car train) and they can only do 75mph so 100mph on diesel is going to have to be downhill and even then will be a struggle.

For comparison they have halve the power of a 195 which has 523hp per car while the 769 has 523hp for 2 cars.

 

[Bletchleyite]

They do, though electric transmission will put that down more efficiently and spend less time keeping transmission fluid heated up.

 

[Optom1]

It shoud easily be possible for 769’s to achieve 90 + in the future, as the incredibly heavy class 40’s (2000hp) achievied 85 mph on the level at Thirsk with ten coach loads.When 769’s eventually start running from Oxford we shall see
