More rush-hour delays for Tube travellers

Tube travellers endured further rush-hour delays today with problems affecting three lines.

Signal problems hit services on the western sections of the Piccadilly and Metropolitan lines.

And a defective train caused delays to services on the Jubilee line in the Wembley area of north west London.

Underground services have been beset with problems in recent weeks, with peak-time travellers often delayed.
