Cheers for the info everyone. If I go down to Weymouth for the day this summer I wound much prefer to go down there and back on an HST for a more comfortable journey really instead of the usual 2 or 3 car DMU which can be crowded and noisy! Rather than specifically going down there and back for a journey on an HST. I got on an HST on a Saturday last year from Yeovil Pen Mill-Bristol Temple Meads, and the Quiet Carriage I was in I practically had all to myself!
A Class 67 there and back though on Saturday 3rd June though. Wow! That is something a bit more special! And I'd really want to get a journey on that there and back that day! But I can't as I'm rostered to work that particular Saturday!
Looks like it will be a pleasant day to go down to Weymouth next Saturday. Sunny and 20C forecast. But Bristol is expected to be hotter at 25C! Hmm.. might wait till later in the summer to go down there!
