While Sarah Little posted: "At least Southeastern are being inventive about their s--t service."
This sums it all up rather well:
A spokesperson for Southeastern told i100:
We know that sometimes it seems that if it is not leaves on the line or snow on the track then it is some other weather issue.
But actually glare this morning made it impossible for some drivers to see the full length of their train in their mirrors before leaving stations.
When this happens they have to get out and check to ensure everybody has got on or off their train safely before they can move. This can take a little more time but thankfully for all it doesn’t happen very often.
