I noticed a special train at Plymouth yesterday, Friday 10th at about 1230. An IET▸ (Intercity Express Train) showing Truro and Penzance. A member of staff said it was for the media and it did look like that as they were all spaced out sitting at laptops. I think it was a 9 car. It was temporarily stopped at Plymouth because of a fatality.
I believe that on the 8th and 9th June there was a special 12.45 Paddington to Penzance and on the 10th June an 08.45 Paddington to Penzance special all believed to be IETs. Presumably there will be some return specials next week?
Btw The Royal train has entered Cornwall (from Windsor and Eton Riverside) and is believed to be stabled at Burngullow.
8 June
5Z31 Stoke Gifford to Paddington (empty stock)
1Z31 Paddington to Penzance (very interesting that these ran via Badminton, and that Bristol in 1:15¾ is doable)
5Z33 Penzance to Stoke Gifford (empty stock)
9 June
5Z31 Stoke Gifford to Paddington (empty stock)
1Z31 Paddington to Penzance (via Badminton)
5Z33 Penzance to Stoke Gifford (empty stock)
10 June
5Z30 Stoke Gifford to Paddington (empty stock)
1Z30 Paddington to Penzance (via Badminton)
5Z32 Penzance to Stoke Gifford (empty stock)
And looking at next week:
14 June
5Z30 0430 Stoke Gifford to Penzance
1Z30 1002 Penzance to Paddington
5Z32 1615 Paddington to Stoke Gifford (this looks like the path of one of the non-running Cardiff trains if ever there was one – that may be the general modus operandi here)
and
5Z31 0621 Stoke Gifford to Penzance
1Z31 1156 Penzance to Paddington
5Z33 1800 Paddington to Stoke Gifford
15 June
5Z91 0718 North Pole to Paddington
3Z91 0745 Paddington to Penzance
3Z92 1301 Penzance to Paddington
5Z92 1832 Paddington to North Pole
(Not sure this is the same thing – it's a 3Z rather than a 1Z, and it's done out of North Pole rather than Stoke Gifford. Also seems to be running on the 18th.)
