Four more months of platform works at Earlsfield station

The next phase in the ongoing improvements to Earlsfield station has been unveiled. The next four months will see a new safety fence installed along platform 1.

While I am definitely in favour of keeping people safe and making it harder for anyone to fall onto the tracks, it seems like an awfully long time for putting up one fence. I'm also not sure of the impact on what's already a very busy platform during the morning and evening rush. How much room will the be between the fence and the pillars for the shelter? Time will tell.
