I don't know how they have the cheek to call it the Stansted Express.
I think the timings on the GEML are partially a problem because of how they intermingle faster and slower running trains. I'm sure the theoretical TT is OK, but how it actually runs is not. I've been on a Braintree train that was pulled over for 5 minutes past Chelmsford, to let through a "faster" train (as per the driver); except that the train let through stopped at Hatfield Peveral, whereas we didn't, so we were held up again waiting for it to clear that station. Madness.
