Suspended due to emergency engineering work?

It was planed late on Thursday afternoon after two days of delays due to defective track in the Brixton area.

I see there is more emergency engineering work from 8pm tonight. No service Victoria-Brixton.

Does anybody know what the issue is with the brand new scissors crossover at Brixton, which was installed with such a fanfare and long line closure only a few years ago?!

Yup but whats wrong with the points, which are only a few years old?

Has to be serious to suspend services.

According to the trackernet, there is an engineering train at Pimlico, on its way to Brixton.

Why not operate a reduced service Victoria-Walthamstow?

You can't have an Engineer's Train working on the line at the same time as passenger trains, as the Slug doesn't have Vic Line ATP.

1) It's not that brand new. The crossover has also been replaced quite a few times over the years.
2) The crossover takes quite a hammering with approx 57 train movements per hour during the peaks! In terms of train movements per day, it is probably the busiest scissors crossover in the world!

So it's probably no surprise that it needs some emergency maintenance occasionally.
