Heading South, I have a serious issue with the fact that when I travel on the hourly LM service Crewe to Milton Keynes Central service, it misses the also hourly SN service from MKC to Clapham Junction by one minute. Passengers are then forced to wait 59 minutes for the next service at MKC. LM arrival from Crewe at MKC is at xx:14 minutes past the hour. SN departure from MKC to Clapham Junction is at xx:13 minutes past the hour. Heading North however the 2 services connect nicely with what is normally an 18 minute connection at MKC. SN arrival at MKC from Clapham Junction is at xx:01 minutes past the hour. LM departure to Crewe from MKC is xx:19 minutes past the hour. I understand that these services used to connect in both directions and it would be nice if they did again. It would take an hour off the journey. What would need to be done for this change to occur? I have emailed both LM and SN tonight asking them to pass on my concerns to the right people within the company.
