Another 399 died at Halfway this morning, though was moved after only about 20 minutes.
Is Halfway fast becoming cursed ground?

Were they not always planned as dual voltage under the current scheme?
I would LOVE to know why this project has been so "difficult". I know I'm no expert, but to this layman's simple understanding...
The most informative (though not very) thing I've read about it was, surprisingly enough, in Rail magazine, I think in the issue before the one that came out this week. It turned out new equipment had to be designed for dual current OLE, which apparently nobody had done before, and all the possible electrical failure modes had to be analysed. (As you may know, AC high voltage and DC low voltage require completely different earthing arrangements.)...and that is precisely my "problem". All anyone ever seems to be able to say is a blanket "....more complicated than expected.......". And my question is - what was, and why was it? The question isn't "what problems"; it's "what NEW problems...." What is so special and unique about this specific little bit of railway electrification - except the voltage?
If I were a cynic (perish the thought!) I'd be tempted to think that someone somewhere actually wanted this project to cost three times what it would have cost any other organisation worldwide, and thus be written off as proof that trains and trams cannot and will not mix in the UK; only in other countries.

I would LOVE to know why this project has been so "difficult". I know I'm no expert, but to this layman's simple understanding:
1: The existing rail track; the trams have heavy-rail compatible wheels, so no change required there. No rocket science needed. Even if it all needed relaying, it's still not rocket science.
2: New points on existing track; ditto
3: New track away from the "main line"; just like existing tram lines, so nothing newly-invented there
4: Catenary; It's being built to be capable of 25kvAC; so it needs necessary clearances - and a bridge needs lifting to make room. Just like on every other bit of overhead electrification NR has done. No rocket scientist's input needed.
5: Sub-station/supply; just like the existing tram so no rocket science here either.
6: New platform to the side of the train through route - just like the existing tram so no rocket science here either.
7: New platforms adjacent to the train lines in Rotherham - I'm guessing these, too are just like the existing tram ones.......
Now what else is there - exactly - that hasn't already been done before, elsewhere, by someone, umpteen times before?
To put it another way
The T&W Metro was extended to Sunderland in April 2002, at a cost £100m. (about £150m inflation adjusted to today).
This required some track lowering and the reconstruction of four bridges. 13km of shared route.
Tram-train: Less than 6km, one bridge, £75m

Seems to be so...probably just because it's the furthest away from the depot on the network, so is more of a pain to get to to sort problems out
No your not but if you get a tram to there you are Livin on a prayer if you actually reach your destinationOT but I hope I'm not the only person who is reminded of a certain Bon Jovi song when I hear that destination...
Just seen a 399 out for driver training
It's a pity that I'm only planning to be back in Sheffield the weekend after. When are they due to be introduced to regular service?
He argues that there was no real need for a pilot scheme in the UK and that it has suffered from the "not invented here" syndrome....Given this wealth of information and experience, there was, in the LRTA’s opinion, no real need for a pilot scheme in the UK. It should have been perfectly possible to have moved directly to an initial installation on a route chosen to best demonstrate the ability to penetrate into and potentially through town/city centres to make the journey that much more attractive (thus generating substantial increases in patronage and revenue). It should also have enabled the removal of local services from parts of the heavy rail network to avoid costly infrastructure expansion to accommodate increasing longer-distance service levels.*
Based against these criteria, it seems unlikely that the Sheffield-Rotherham route would have been the first choice.*
The National Audit Office report from July identified a significant number of failings in the Sheffield-Rotherham project, most of which could have been avoided if the DfT had taken a more robust approach and required a thorough review of the experience in Karlsruhe by all the parties concerned, with the help of its colleagues in the German Federal Ministry of Transport. It seems, once again, that the ‘not invented here’ syndrome has come to the fore ...
According to BBC Look North this lunchtime, the first tram-train starts service today, running on the existing Supertram network.
From the pictures of the interior of the new trams posted on Twitter, my first impressions are "those seats look rock hard"
