@HamworthyGoods -- (and pinging
@yorksrob and
@Chrisgr31 as it's their arguments I'm also piggybacking off) -- I completely agree. Reducing services on commuter lines would be problematic, particularly because many people still work or need to go in to the office on a Friday. Only around a quarter of the workforce can work from home at all, never mind are permitted to do by their employers, who are seeing the drawbacks of perma-remote work.
In the early stages of the pandemic lockdown, the logistics of getting to and from work suddenly became more anxiety-inducing for me than the actual virus was. The day before full lockdown was imposed, only one train every two hours was calling at Reading West, and I was actually signed off sick at work (from the NHS so decent leave allowance, although I'm not clinical- or patient-facing, so I didn't get the assistance given to clinicians who needed to stay away from their families due to working with contamination) due to both the panic attacks and the lack of transport between Basingstoke and Reading.
Whatever you think about removing peak time on Friday morning, it would be therefore erroneous to conclude that Friday morning is a sensible time to reduce services. It would simply feel a bit out of touch with the way things still generally need to work and how season tickets are still useful for those who are five days in office (a lot of auxiliary administrative staff and receptionists etc).
