Weird observation on T&W Metro this morning

[Kryten2340]

Whilst heading to Regent Centre I've noticed that under the driver CCTV screens (the ones which let them see down the platform) at Central, Haymarket and Jesmond there has been signs put up which is basically a black arrow on a white background with a red border and the arrow points to the platform. I can only imagine that this is to remind the driver which doors to enable but do they really need such a reminder? Are the visuals as the approach the platform and the CCTV not enough?

I haven't seen them but will look out for them when I'm next on. Black arrow on white background normally goes with a spped restriction sign for a diverging route, but won't be the case at those stations.

They've done the same thing on the southbound platforms at the same stations. Black arrow on a white background with a red border pointing to whichever side the platform is on so to the left for Jesmond and to the right for Haymarket and Central.
Monument has nothing on either side. Well platforms 1 and 2 that is.

I'll have a look next time I'm on the system - probably is just a reminder (like SPAD reminders for conductors on some trains).

Also, it might be in place for some engineering work involving those stations - might be running wrong line? Shot in the dark with that one.

I was checking this again today and the signs are about the same size as the ones that indicate a speed restriction on a diverging route but the arrows on the ones under the CCTV screens are half the size. Only take up half of the length of the sign.
