Big problems in the Bournemouth area from about 17:00 to 19:00 last night, with nothing moving due to a signal power failure.

Not really much to comment on, except I am sure (ish) the same reason was given for similar big disruption on the morning of 16-Oct.

Is there something particularly fragile about Bournemouth signalling's power supply..?

You’re not imagining it, there’s been at least one other occasion recently.

from what I can see, Power Reduction Mode has been implemented from Weymouth to Brockenhurst, something to do with the railway transformer is powering that whole section without support. I’ll see if I can find out more.

There were some power issues a couple of weeks ago I seem to recall being read out on the travel bulletins on the radio however they sounded more like power blips akin to what happened in August.

The incident on 16th October was definitely described as a signalling power failure; I was travelling at the time and the station staff at Brockenhurst were explaining to passengers that all the lights and indicators had gone dark in the signal box at Bournemouth. I think I also saw a picture of a dark signal head on Twitter.

Pointing towards a UKPN fault maybe ?

Scottish and Southern rather than UKPN
I thought UKPN (UK Power Network) maintained the distribution network for the various supply companies, in the same way Network Rail supplies the track etc. for the various TOCs?

Did this one incident run for two days? Just that your thread title refers to the 9th, yesterday, but the description refers to ”last night” ie the 8th?

Sorry my mistake, it was the 8th... there was something said about power supply problems yesterday (9th) between Bournemouth and Weymouth, but I don't know if that was signal- or traction-supply related...

8th and 9th had power reduction mode for DC traction which caused delays to services

Yes that was certainly being announced at Southampton Central yesterday. Along with another power failure at an unspecified location causing a delay. However as 10 minutes earlier that delay was due to lack of train crew who knows what the real reason was.

to be fair, it’s likely the traincrew were delayed on their preceding journey... short term planning diagrams tend to use the minimum connection times.

There were signal problems in Bournemouth yesterday early morning (19th Nov) too, although not as serious as the previous two occasions. It wasn't specified this time that it was a power failure though, does anyone know if it was that or something else...?
