Audley End-Cambridge North closure, 16-17 April

[HughT]

According to the Greater Anglia website, the West Anglia line is closed between Audley End and Cambridge North, Thurs 16 April to Fri 17 April

But their Journey Planner seems to show direct services between Cambridge and Liverpool Street as normal (on the Thursday at least - that's all I was interested in).

A search on the National Rail Status and Disruptions page fails to turn up anything relevant. And the NR Journey Planner doesn't seem to think anything is planned. Given that this is only just over a fortnight away, one would expect NR to know about any disruption...

Any ideas (or inside knowledge)?

 

[Class 170101]

RTT shows a bus between Bishops Stortford and Cambridge replacing the normal last train between those points.

It is possibly a typo.

There is a block north of Audley End on Saturday 16 and Sunday 17 May.
