That was sort of my point in starting this thread. I would have thought most of the answer to this question would be through risk assessment and analysis of available mitigation within each option. This approach should lead you to roughly the correct answer. I am sure such an exercise has been...

Many thanks. What is the limit of electrification via Atherton?

In terms of capital costs, there is is plenty of money out there at a low rate for things like lighting replacements. Some lighting manufacturers can offer asset finance on lighting at about 5% and the payments sculptured to the savings profile so that NT/the TOC is always in the money. If you...

When was that? As a Huddersfield fan I can honestly say the only significant trouble I have seen around the ground and town coincided with a certain London club coming to town. Huddersfield is a very family friendly club. Watford is a really odd one for trouble to flare up at!

I don't know the route well. If you are travelling from Manchester to Southport does the train pass through Lostock and is that the limit of electrification in the Southport direction?

Is there not sense in Northern taking the 185s to replace the 158's intended for Northern Connect and then send 158's to Ireland to see out their last few years as the required stop-gap? In general I would agree it feels very much like Northern needs further capacity and so losing units might...

Let me guess, Thameslink get to claim energy costs from the contract as a pass through and so no incentive on them not to throw our money down the drain.

Sorry, I probably should have said in my intro that I am thinking mainly of power to fixed infrastructure rather than rolling stock. That is because I suspect rolling stock would deserve it's own thread. That said I find the emerging position on traction power for rolling stock fascinating and...

The railways obviously use huge amounts of power. How good is NR and prioritising saving cash on this, as well as reducing emissions? As an example I have just been through the Thameslink core. All the lights are on at the OLD Kings Cross Thameslink station and at at City Thameslink (closed...

As I asked the question, I will decide the level of detail I was seeking thanks ;) To clarify though, the point of particular interest for me is whether the ROC approach vs what I suppose was a distributed system is more likely to cause problems across a whole area versus delays to services on...

Well that depends upon the impact that would cause. If there is no ability to get an alternative up and running in a reasonable period, it would very much trouble me. There are also a whole host of scenarios other than a catastrophic fire. I didn't ask for huge amounts of detail in the OP and...

I have found this article from 2017 which should assist in the debate: http://www.railtechnologymagazine.com/Rail-News/orr-warns-that-roc-risks-not-yet-adequately-assessed-by-network-rail I have to say I find the line from NR about risks not being realised until these centres have been in...

I am not a railway professional (like Grayling - I don't even run the trains) and so forgive any incorrect terminology. I have been caught up in the mess in West Yorkshire area twice, once when I think lightening hit the ROC and once when there was a power cut. I was stick at Victoria the...

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.

It has not been great recently on getting stock on the rails into revenue earning service has it really. The guys who delivered the infrastructure on Crossrail must feel pretty aggrieved about how the stock and signalling has pushed everything back so far.

I think they look great! After many many years going back and forth on this line this is the first intercity stock I will have ever experienced. A long time overdue but welcome nonetheless. I think there will be problems with dwell times and that is a concern with current performance on the...

On mechanical condition, have Northern looked after theirs better then? It seems extraordinary that poor maintenance has lopped 15 years off the life expectancy of the Heathrow Express trains. The 333's still feel like the most modern train on the east of the Pennines by far. For me, they are...

2 quick questions: 1. I have noticed the track coming into Central from the south seems to be jointed. How does an intensely used section like this manage to be quite ancient when plenty lesser used bits of the network have continuous weld? 2. Could the Kirby service be extended to Wigan...

I If a few houses in Mossley are being used as a significant reason for not electrifying one of the most important train lines in the country the we can all go home. No point in having any ambition for the north. Forget any Brexit dividend if this is the approach as well. Westminster is far...

Why can't the houses at Mossley be CPO'd? CPO is always contentious and obviously causes distress to the existing homeowners which is not ideal. However it is also there to be used in just this sort of situation. Any NPR alternative route is many years away. The cost of CPO of these properties...
