Due to the Jubilee line been messed up this evening, ended up going to Vauxhall to catch the train. So for 10 minutes I sat, starring at the MI6 building opposite the station. A very imposing building, minimal windows, full of cameras covering multiple approaches. Except for one, at the top of the building. I’m convinced the security team using it are train fans. As the trains went through the station, the camera kept tracking them back and forth. left to right. I’m pretty sure they got most of the engine numbers!
