This morning's journey to Canary Wharf was bad due to the Jubilee Line being part suspended and Bank being closed due to overcrowding.
Unfortunately, the day is now getting worse.
Currently I am sat on a Chiltern Railways' train in West London, stuck behind a broken down Wrexham & Shropshire service. This is not good because they are apparently having to send a fitter out, by road.
Have been stuck here half an hour so far.
Still, I suppose it isn't a good idea to run a train with defective brakes.
No doubt more to follow later.
