Two recent examples -
Travelling back from Birmingham to Dorking the other evening, I took XC to Reading then GWR to Dorking. The 1932 from Reading to Gatwick was delayed en route and a crowd gathered on the platform at Reading, including a large group of drinking lads. 'Noisy, but good-natured' would be a kind description of them. It was eventually decided to use the train already at the platform for the train and swap over with the incoming late arrival for the following stopping working.
When the driver turned up and opened the doors, all the drinkers piled into first class (it was 166205 as it happened, with the leather seating) as predicted, and I managed to get a seat there too. They remained noisy and foul-mouthed (but still good-natured) all the way to near Guildford when a woman stuck her head into the compartment and asked them to behave/be quieter. I'd been using my earphones to blot out their noise. As we stood at Guildford (about 20 late) I noticed the scrolling message had changed to next stop Redhill (i.e. omitting Dorking and Reigate). I scurried off and asked the guard (hidden at the back of the train as usual) if we would stop at Dorking and he said no as if it had been the plan all along!
If a woman passenger was able to ask the yobs to shut up, why couldn't the (burly) guard have deigned to emerge from his den, and enforce first class as well? I'm pretty sure there was no announcement as I could still hear the yobs over my music, and would have heard the p.a. too. Apart from the lack of notice, GWR are far too fond of missing out stops when behind time.
The other one was on a Thameslink working down from Blackfriars a couple of days ago, when we stood outside Redhill for ages (as usual) and then were told that we would omit the stop owing to a medical emergency meaning no platforms were available, although as we passed platform 1 (reversible) was empty! We were told to travel via Gatwick. Hourly connection to Betchworth missed yet gain!
