TUBE and rail passengers are suffering this morning due to numerous line suspensions - not all weather related.
Transport for London said there is no service on the Metropolitan Line between Harrow-on-the-Hill and Watford, Amersham or Chesham due a signal failure at Harrow-on-the-Hill.
The rest of the line is already experiencing "severe delays" because of late finishing engineering work.
London Overground trains are not running between Willesden Junction and Richmond due to the ongoing snowy conditions while the Bakerloo line is enduring "minor delays due to operational issues" and the Piccadilly is current enjoying a normal service.
The Met Office forecasts that the freezing temperatures in Harrow will continue for the next five days, with the highest daytime temperature being 1°C tomorrow (Tuesday).
It will plunge to -3°C around 9pm this evening, warming ever so slightly at that time on Tuesday and Wednesday and falling back to -3°C on Thursday.
There is no further snow predicted until 12noon on Friday and the rest of the time is likely to be overcast and cloudy with ice warnings remaining in place for tomorrow.
