Definitely a new line towards Braintree, Witham and Chelmsford would be brilliant. The bus service for airport workers is absolutely terrible I have colleagues who rely on lifts or have to wait 2 hours for buses at night as their is no buses. And during the day the services are just about every hour and they are always full. Stupid really when buses towards Harlow are every 10 mins during the day.
I know the Airport wants to make staff travel via public transport better though.
