Flawless journey to Yatton.

From Yatton cycled along the north side of the Yeo Valley, over the Mendip edge to Midford and down the Two Tunnels, changed mind about taking train from Bath and cycled back to Lawrence Hill by the Bristol-Bath Railway Path. Interesting that cycling 30 km seemed more attractive than going 3 km into Bath to try the vagaries of the train service. Possibly because of a vague hope of a warm midsummer evening that did not really materialise combined with the assumption that an 800 would turn up.

Memories

Both the Twin Tunnels and the Bristol to Bath path, once the domain of the lumbering giants of the steam age, are now the preserve of the excessively fast speeding cyclist. Both paths remind me of the last time I travelled in the front of a first generation DMU, some time in the eighties. In the sixties this had been a treat, in the eighties, being older, the sight of a hulking great English Electric Type 3 hurtling towards us on the other track was quite offputting.

Preservation Progress


The 4F (?) boiler in the scrapyard/heritage railway at Bitton looks just as it has for the last score of years.

Cold Hole

The way the cold flows out of Combe Down tunnel, for at least 100 metres towards Midford is striking, despite the approach not being a cutting but a relatively wide short valley. Does this also happen on live railway tunnels?

Service collapsing all around.

Made good time from Mangotsfield, reaching LWH about 1900, so had fifteen minutes idling on LWH listening with alternating smugness and apprehension to the train service collapsing around me. Smugness as the Filton Abbeywood train was cancelled (More trains than usual needing repair at the same time) then the Avonmouth to WSM train (Fault on this train). Apprehension as the 1917 for AVN became the last train standing, so sure to attract attention, also at the possiblity that the WSM bound train might be blocking the SVB line.

Passengers calm

At Clifton Down (CFN) about a score of passengers, possibly increased by the WSM bound cancellation were waiting calmly for the train going the other way, reading books, phones, and so on. Our guard shortly announced this as delayed, possibly 'objects on the track'. After about ten minutes he got out of the centre doors and walked forward, shortly after which the other train arrived, sending a passenger for it who had just come down the ramp on our side, presumably in search of information, scurrying back across. About 11 min late at SML.


PAYG

ALl PAYG correct, except that the system reported travel times in GMT or UTC, which it had been doing so since at least Saturday morning.

Puzzlingly angled cycle mount:

The above fairly new type of angled cycle mount puzzles me. Whether it is an innovative solution to the fact that the class 166 space is not long enough for anything but a 26 in mountain bike or a racing bike, or a random selection I can only guess.

For a tunnel of its length, Combe Down (note - only 1 “o”) is unusual (and notorious) for having no ventilation shafts - which may make a difference. “Live” railway tunnels will also experience a partial piston effect each time a train goes through which will alter the air flow, so the effect may not be as noticeable. The Midford end of the tunnel does emerge into a cutting - albeit briefly - but enough to shelter the alignment from breezes.
