Not sure what has happened to cause this drop in unit availability!
Not been the best of weekend for it to happen being a bank holiday/half term week. |

Surely though if the HST▸ was that stretched, they wouldn't have been able to diagram that additional HST last Saturday? Wouldn't that set be available at the same time next Saturday?

HSTs▸ to Weymouth aren't a feasible option. 8 carriages is too many, and they require a special type of bogie to avoid risk of shorting out on the 3rd rail.

the only way hst's would run to time on that service without removing stops is to remove coaches, too much messing around for one service

Hmmm - while I understand about the length of the trains being a problem - I cannot see the 3rd rail being an issue.
HSTs▸ have run regularly to Bournemouth, Poole and Portsmouth in the past, as well as diversions into Waterloo and i'm told no modification had to be made to them. If the risk of them shorting out was that great, HSTs would be banned from 3rd rail lines as per 143s surely?

For Hsts to run on 3rd rail they need Short Swing Link SSL▸ bogies. XC▸ sets had these. |

this is a wild guess... im guessing the chance of actual contact is very slim if not impossible? is it to prevent arc'ing

The Sprinter Meister is the person to ask. I read a detailed answer of his elsewhere today.

HST▸ was definitely a 'last minute' decision caused by acute set shortages mainly caused by the fatality near 'Tuckers' crossing, Bradford on Avon. Set was operated by a 'High Speed' (HSS▸ ) crew (Bristol based presumably), as they had the traction knowledge, with them being piloted by a 'West' crew (Bristol or Westbury based), as they had the route knowledge.
One way an untrained eye can tell if an FGW▸ HST set is formed of SSL▸ fitted vehicles is that the letters SSL or LSL‡ are usually displayed at the ends of the carriages, depending on which type is fitted.

Indeed. On Saturday 2x158/9s and 1x150/2 were taken out for inspection after than fatality.
8 carriages is quite a substantial amount!

To be fair this is not the first time a FGW▸ HST▸ has run over 3rd rail territory this year, dont forget they sent a HST set down to Fratton in January for the Portsmouth vs Swansea match.

William Huskisson MP▸ was the first person to be killed by a train while crossing the tracks, in 1830. Many more have died in the same way since then. Don't take a chance: stop, look, listen.
"Level crossings are safe, unless they are used in an unsafe manner." Discuss.
