TPE Nova 1 Class 802/2 Progress

[59CosG95]

They'll be testing on different routes to the rest of the units and it's probably a lot easier to keep a separate unit so TPE's testing isn't contingent on any variations to the testing regime for the other operators. Since they're so similar, no harm in building one early to get all the testing done with. Seems fairly sensible to me.

Indeed, the last thing GWR need is TPE pinching one of their units for driver training.

Also the TPE units have different engines (940hp vs 750hp) due to the hills they will climb.

I believe that's false - it's the same engine. 800s and 802s are all fitted with the same 940hp engines. Those in the 800s will reduce output to around 750hp at a certain speed, but even they are 940hp engines. All 802s whether GWR, TPE or Hull Trains, to my knowledge, are 940hp throughout.

 

[TBSchenker]

Indeed. The difference (as well as the higher output of the engine) being the 802s have larger fuel tanks because they will be running on diesel longer?

All the engines are the same, it's the way the engine management software is configured that changes the performance characteristics.

How do these unit's engines compare with 185s?

How do these unit's engines compare with 185s?

Higher power per engine, but fewer engines per train given the number of carriages (3 engines on a 3-car 185 giving 1 engine per car vs 3 engines on a 5-car 802 giving 3/5th of an engine (on average) per car).

 

[samuelmorris]

engine power per metre length wise, 5-car 800/802s are about 66% of the power of 185s (22hp/m vs. 33), 9-car versions about 62%. There will also be differences to consider with comparative efficiency between the hydraulic transmission on 185s and the electric transmission on 800/802s, as well as the fact that above 30-40mph, the power output of 800s is further reduced by 20%.

 

[anamyd]

what about the type of engine as well...? the 185s have 19 litre straight sixes and the 802s will have 21 litre V12s

Shiny, but want to see the front and inside

Not finished adding the vynil yet and the interior is the test one so nothing to show.

 

[samuelmorris]

Yeah fair enough, I thought that may be the case.

 

[ash39]

Without a doubt, this will be the best livery on an 80X series train seen so far. Looking forward to seeing the finished article.

 

[samuelmorris]

Agree, but I don't think the GWR livery is bad, it's probably one of the best things about the train.

 

[Ih8earlies]

I may have missed it if it has already been posted somewhere - but is there a layout map of the TPE 802's? (Assuming it might be different to the LNER 5 cars)

 

[TBSchenker]

It saddens me that liveries are being made from viynls . I understand why, speed and probably cost of getting a train done in New colours, but after a few months in traffic the seams start getting dirty, and quite a few of the 185s are getting damage by the doors .

I understand why the 185s were viynled but the 802s could have come painted . Are the Mk5s and 397s viynled or painted?

A mix.

I wonder what the environmental consequences of vinyl v paint are. The railway is meant to be considering that sort of thing. I have no view or idea on what the respective impacts might be on a whole life basis, but would be interested to know.

Depends on the paint composition, as well as the type of stickers used in the "vinyls".
The "vinyls" might not necessarily be polyvinylchloride (i.e. PVC), they might be another similar polymer (thermoplastic polyurethane, for instance), which is often eco-friendlier.
I don't think Joe Public would examine the polymeric composition of every sticker on every train with vast scrutiny, however.

A train-borne environmental consequence of vinyl vs paint is the corrosion issue; FGW reverted to paint after the Dynamic Lines vinyls on some of their 166s started peeling - this left a small bubble between the vinyl & thr bodywork, allowing moisture to form and corrosion to occur.
Topically enough, some of the vinyled 800s (the /0s) are looking much the worse for wear than the 800/3s, 802/0s and 802/1s, which were all painted.

Any word on when construction is due to begin on the 'main series' Class 802/2 units?

 

[Charlie Smythe]

Any word on when construction is due to begin on the 'main series' Class 802/2 units?

I am fairly sure that construction has started already.

Nearly all the trains that TPE ordered are either fully built or under construction.

 

[Fez14]

will these be tested on the Pennine corridor anytime soon, or sticking to east coast mainline for now?

 

[BMIFlyer]

Soon, yes.

[Thomas6187]

It would appear that 802201 & 802202 are coming over the Pennines tonight. There are moves everyday this week from Doncaster to Crewe, then some runs between Crewe and Warrington BQ, before returning to Doncaster

5Q51 Mirfield-Crewe via Piccadilly and Return

 

[LNW-GW Joint]

Presumably not going to use the wires at any point?
Must be the first appearance of any Hitachi stuff on LNW Route?
I can't remember 395/385/80x showing up before.
It will be interesting to see if there are any OHLE compatibility issues once the pan goes up.

 

[TBSchenker]

East Coast say their IETs have been tested on all their routes and diversionaries,so they will have run to Carlisle at some point.

 

[YorkshireBear]

Modern Railways are reporting a fix for the ongoing issues with using electric on the North ECML too. From how it is reported it suggests a train fix so hopefully that fix will mean no issues running on wires around Manchester and that will be tested soon.
