Stagecoach has resumed testing of an amphibious bus service in Glasgow after technical problems halted the first trial.
The "amfibus" was grounded less than an hour after taking to the River Clyde on Monday when an airbag popped out from part of the suspension.
The £700,000 Dutch-made vehicle can carry up to 45 passengers. The vehicle runs like a normal coach on the road but when in water uses a hull to float and is powered by twin jets.
It is one of several schemes which could be used to replace a ferry service between Renfrew and Yoker, which is to be scrapped by Strathclyde Partnership for Transport in March to save money.
