<Pendantic> Thameslink opened in 1988 </Pedantic>

I think you mean 377s/387s have run as 12 cars at 100mph on the MML. 319s were restricted to 8 car formations.

No Motherwell was brand new. It did incorporate the earlier interlocking at Newton though

Just to add that it had a major upgrade in the early 70s as part of the extension of the WCML electrification from Weaver Junction to Glasgow. The 1961 ocs panel was replaced with an NX panel and the control area greatly extended.

There have been incidents where systems which were thought to be fail safe but turned out not to be. One I can think of was on the Washington Metro where a track circuit module failed in such a way that it failed to detect a train resulting in a fatal collision. I can think of others in the UK...

Units operating on DC generally experience more power interruptions than units operating on AC so that shouldn't be a problem at all for 319s as they've been dealing with it for years

Two problems with the 332s being redeployed. 1. They don't have AWS/TPWS 2. Mechanically they are not in the best of shape That means they will need serious money spent on them if they are to be re-used. Indeed it is possible they would have needed serious money spending on them if they...

It's been resignalled since then when Victoria (SE) panel opened in the 1980s

Pan down is permissible anywhere at any speed. Pan up above 20mph is only permitted at designated changeover points (ie currently Moreton, previously Maidenhead). The designated changeover points require the ole to be specially tensioned.

There are locations (usually around S&C) where the running rail nearest to the conductor rail doesn't carry traction return current. Hence trying to use an SCB will a. not work and b. cause havoc with signalling circuits and so the protective cover on the underside acts as a warning and a...

That'll be the flawed assumption that NR/DfT would deliver the upgrades and new trains on which the franchise contract was predicated.

DOR deferred some fleet maintenance which is why their financial performance appeared better than it really was and why there have been Class 90s working for VTEC whilst the maintenance backlog is addressed.

The 85mph limit dates from when the layout was changed at Rushey Platt to allow up stopping trains a faster run into the station.

Thanks for the replies.

I note that a condition of a Senior Railcard is: "Your Senior Railcard is NOT valid when travelling between two stations inside London and the South East area during morning peak time." Does this mean that a Senior Railcard holder who purchases an ALR cannot travel from say Brighton to...

Takes me back to the early days of AC emus and the exploding Class 303s.

Should be no problem but I can tell you from personal experience that it is. I've had a few run-ins with LO RPIs who claimed an ALR was invalid on LO because of variations on the well worn theme of "LO is part of the Underground and not National Rail". My view is that TfL management do...

If you're going that way then it's better to change at Balham rather than Clapham Jn if you have limited mobility.

From the videos it sounded to me like both were under power

The retained HST trailers are getting power doors
