What if....! (netoworker question)

In theory....if Connex wanted more Networkers (i know unlikely due to orders for electrostars) but who could build them......due to copyright sort of stuff......?

i mean if memory serves the class 325 was based on the networker and was built by "ABB" which i think but am not sure is adtranz now bombardier......

in theory could bombardier build more networkers.....?

Possible, but Connex did put an order in for several class 376's to replace the Networkers.

I guess the 325's could be turned into a 465 or a 365 as they have dual power.

Does anyone know what will happen about the 376's now? They are 5 Car, which is a better idea, but I don't think Connex will be willing to fund anything, which means we are back to square one!

There was also some discussion about the 325s displacing the 323s on some of the northern routes with the 323s transfering to the Midlands. I suppose we will have to wait and see what happens to the units. I cant imaginbe they will be scrapped because they have only been running since 1995 or 1996!

On a semi related note, did you know the class 91's + Mk4's [Intercity 225] was planned to be replaced by the Class 250.

But they are relatively new units? I'd be mighty surprised if GNER wen't ahead with that....

Sorry to sound ignorant, but what is a Class 250? Ive never even heard of them!

not a class 250 but like the ic 125 aka the class 43

the ic 250 if my memory serves is the never produced class 93

So the Class 250 is AC electric then, like the Class 91?

i know that this is not onna happen which i did ut in the inittial post however would it be possible and who has the rights to build em...?

Someone correct me if I'm wrong; I'm sure the 325 (the parcels units, right?) were equiped with updated 319 control gear which was 'chopper' DC control. The Networkers had 3 phase inverters. Also, the 325s had buffers and draw gear where as the Networkers had tightlock couplings and auto-couplers.

The 325s definately have buffers. Compare and contrast:

the 325's were built so that they could be converted to passenger use however the cost is so substancial that it would be hard for any toc or rosco to justify spending on the conversion

however if they did we could see networker derived trains in regions other than the south east

The Networkers were built by Alstom, and are a pile of . just like the Juniper. I know a highly respected Alstom trainer who will tell you that aswell {but not on places like here}.
Networkers - you wont get anymore, as Alstom built them, and they arent going to build any more trains in the uk {well, i think they are building some trains for the underground, but thats their last order}.
They lost billions on the Networker and Juniper.
You want examples?
The compressor on the 458, is powered by the auxilliary converter. The contact to energise the Auxilliary converter, is operated by compressed air. 458's have air rentition tanks, that retain enough air up to a week {even if they are not on the conductor rail} to operate the contacts for the auxilliary converter, which will bring the compressor online, and provide you with compressed air.
The truth is, those rentition tanks actually retain air for about 5 minutes. So if you are on the mainline, and you suddenly lose all you're air, you are screwed in more ways than one.
To get you're train working again, you have 2 options......
Bring another unit {most types will do, be it slam door or modern} up to the failed unit {either end will do}, isolate the air cocks between the 458 driving motor coach, and the next coach {either you're MOS or TOS}.
Then pump up enough air on you're DMOS, using the compressor on the good unit to pump air through an emergencey main res pipe between the units, to operate the contacts to bring the auxilliary converter online, to bring you're compressor online, and open the cocks between coaches again.
If you are unlucky, and get stuck somewhere where you cant get assistance, you have to get a foot pump, with a specially converted nossle, plug it into the unit, and raise the air pressure to bring you're auxilliary converter online and so on.
On the old stock, we just turn the key and the compressor comes on without all that rubbish {all right it still goes through a few sets of contacts, but they are electrically operated}

hey hey did u read the original post i was just asking who held rights for the building of them....i know they aint the best on the tracks but they are what i travel on and they are better than some i have traveled on.
