Obstruction in Balcombe tunnel?

[Islineclear3_1]

Heard a report of a metal object fallen on the track in Balcombe tunnel...can anyone confirm? Some cancellations on Brighton line not helped by a fatality at Glynde

If that's the case it's likely it's a part of the drainage system which I believe was recently renewed

Is this likely to be the rainwater catchment sheets that were subject to a RAIB report after a previous collapse a few years ago? (2011- report issued 2013)

Possibly bad news for NR if it’s the same mode of failure...

Early on the morning of 23 September 2011, the crew of an engineering train passing through Balcombe tunnel observed that part of a large steel structure mounted in the roof of the tunnel, spanning over both railway tracks, was sagging down. An emergency inspection found that on one side of the structure, three supports had become detached from the tunnel lining leaving a 12 metre length partially supported.
