Intervention meanings

[Legolash2o]

Hi all,

I have recently put in a request for interventions required for a W12 gauge clearance. It mentions some of the modifications are "Track Slew" (platforms) and "Coper realignment" (some platforms and underline bridges).

What do they mean and what does it involve?

Slewing means moving the existing track off its original course so it's shifted to one side of where it originally ran. In the case of platforms, the track is shifted away from the platform edge for the length of the station.
Coper realignment is replacing the coping stones on the edge of structures to either create more room or fill in a bigger gap.
