You’re certainly right to highlight the much better bus service, though it seems to be quite a slow 35-40 minutes from Kenilworth to Coventry station.
7-8 minutes on the train. Let’s hope they return soon.
Today at least there has also been a rail replacement bus service running - for example
https://www.realtimetrains.co.uk/service/gb-nr:S10564/2021-12-27/detailed15 minutes from Leamington Spa to Kenilworth and another 15 minutes on to Coventry, continuing on to Nuneaton.
Yes, that's better than some routes where the service is completely suspended such as Cardiff to Ebbw Vale and the new service from Newport to Crosskeys today, though that is due to signalling staff shortages I think? That's a 'do not attempt to travel' today.
It highlights well how a planned temporary service suspension with a planned rail replacement bus service can sometimes be better than a short notice suspension of service or ad-hoc cancellations where buses can be difficult to arrange.
Like I said originally, it's a conundrum as to which option is best.
