I travelled by train for the first time in at least a year, on a Saturday, today. Travelled from BPW - CDF and return with GWR.
Weirdly, and surprisingly, both journeys went smoothly. 3 of us travelled on a group save return for £30 for the 3 of us (a tenner each) so reasonable value. Got seats on the train over, albeit some of the last seats in coach B. Arrived into CDF just a few minutes late.
Coming back it was weirdly quiet. Got a table seat in coach B again, with only around another 6-8 people in the whole coach. Arrived on time in BPW.
When walking around the shops at Cardiff, I did notice the main car park was full with a long queue of cars waiting to get in and some traffic queues on surrounding roads.
I will always prefer the car for convenience, especially for longer journeys but the main exception being when I’m travelling into a major city centre. I’ve now moved towards driving around half way by car to a suitable park & ride type station (Longbridge for Birmingham, BPW for Cardiff, Didcot for London, Hooton for Liverpool etc) and then getting the train into the city itself. There are some reasonable value ticket prices out there on GWR for shorter journeys to be fair, it’s the longer journeys that are overpriced.
