I have never heard of those lines. I have travelled on many lines in the UK rail network, like South West Main Line, Wessex Main Line, Portsmouth Direct, East Coast Main Line, West Coast Main Line, HS1, Great Western Main Line, Reading-Basingstoke, Reading-Waterloo, Brighton Main Line, North London Line, West London Line, and so on. Even in the most rural bit of the network there are trains every hour, except Beaulieu Road. The only line which I know and don't have an hourly service is Heart of Wessex, connecting Weymouth and Yeovil, and I have never travelled on that line.
