Just fallen victim to some more timetabling quirks from c2c. Sat at Limehouse waiting for the 00:19 to Grays and lo and behold another train passes through to Grays without stopping at 00:06. What could possibly explain not running the last trains of the day as all stations services? Additionally - this has been another weekend of only 2 useful tph via Grays as the Upminster shuttles are timed so closely to the direct London trains that there’s no point using them. Just wondering why frequencies are so low on a well used route. And why the 4 tph off peak can’t be spaced out in a way that’s more useful and closer to a turn up and go service?
