Bombardier Flexity Swift vehicles have been supplied in two different versions. Of these vehicles, 54 are the 25-metre long U5-25 version and 46 vehicles the 50-metre long U5-50 version. Both versions are two-way vehicles. In terms of internal fittings, VGF has largely followed the style of the tried-and-tested S carriages. Alongside many visible and invisible improvements that will make travelling safer and more comfortable in future, the most exciting improvement is that all U5 trains are fitted with air conditioning.
