By the way, how’s the reliability of the train service itself in general? Is it OK or am I going to hate my new life??
I live nearer Cambridge than Huntingdon, but I commute from Huntingdon daily. I’m not a fan of Cambridge station, too small, terrible parking facilities and the city is a pain to get in and out of, for your sake I hope you are walking/riding to the station.
Overall you need to accept that 1) it will be busy, 2) you have no control over the lateness of a train, so don’t get wound up by it. Reliability, well I’ve been very late home 2, maybe 3 times since January, so on the whole I’d say the line I am using is pretty good, given that it’s KGX as well most trains suffer similar fates.
As for mobile signal, my current phone seems to not want to connect to mobile data reliably, can’t tell if it’s the sim or phone, but as others have said, expect dropouts along the way.
