For Hsts to run on 3rd rail they need Short Swing Link SSL▸ bogies. XC▸ sets had these.
After reading this post I've been keeping an eye out and haven't so far spotted a single FGW▸ HST▸ set that does not have all vehicles marked "SSL", so from a purely technical point of view regular HST services over the 3rd rail could be feasible. |

From an operational point of view, platform length and slow acceleration would be the main barriers I suspect. 8 Coaches is too long for a number of stations on the Portsmouth-Cardiff route for instance, shame since a reintroduced Portsmouth to Penzance service on a HST▸ would be quite a pleasant ride I'm sure. As far as I'm aware the trips down to Fratton were at police insistence- Imagine the scene if the away supporters got to the station and saw that the 17.31 was a 3-car 158!  |

There are trailers which don't have SSL bogies but I am sure I read somewhere that what is now wrote on the trailers is not necessarily the truth. |

Reading the Wikipedia page on Cardiff Central it currently states that FGW▸ will run a Cardiff (or wherever in South Wales) -> Weymouth train in 2012 prior to the Summer Olympics. Given Wikipedia's renowned unreliability for fact, Can anyone here confirm this? |

Probably hasn't been finalised so I wouldn't trust anything on Wiki that isn't referenced.

Sounds perfectly plausible though - no-one said anything about using HSTs▸ in this case. It's not so many years ago a lot of Weymouth services originated/terminated at Cardiff. I used to catch one such regularly on a Saturday morning which always switched to an ATW▸ crew at Bath for some reason.

As far as I'm aware the trips down to Fratton were at police insistence- Imagine the scene if the away supporters got to the station and saw that the 17.31 was a 3-car 158! Are there many sections on the Cardiff - Portsmouth route that have a speed limit high enough to justify having some permanent HST▸ services? I'm thinking that during rush hour and popular off-peak times, a couple of HSTs would be more than welcome serving this route, especially if they reduced the journey time slightly! |

Almost certainly not!
I don't know if an HST▸ would be able to keep to 158 timings either - it may be that the acceleration isn't good enough. Then there's the issue of SSL▸ vs. LSL‡ bogies over the third rail and it all gets rather complicated!

Bath - Bristol is probably the only section where an HST "trumps" a 158 on top speed. |

The Fratton - Cardiff service went via Eastleigh and Chandlers Ford apparently because HSTs▸ are too heavy for the Hamble bridge near Bursledon, therefore missing out Southampton. I guess that wouldn't be too successful an alteration in the peaks...

Or at all! Travel to Southampton is one of the more popular 'flows' on that route. Certainly it's the only journey i've ever made on Cardiff - Portsmouth trains in the direction of the south coast! |

Wow I am suprised. I would not mind sitting in the quiet carriage on the way to Weymouth.
