There's disruption on the Stansted Express service between Liverpool Street and Stansted Airport due to emergency engineering works between Cheshunt and Broxbourne.
Passengers for Stansted Airport are advised to travel to Witham, where a replacement bus service will transfer them to the airport. There is no estimate for when a normal service will resume. The work is also affecting Greater Anglia services.

Greater Anglia train operator Abellio says it's made real steps in customer service and punctuality in its first year in charge.
Greater Anglia have apologised for the delays that have disrupted services today
