The local railway lines in Vienna, such as the Baden line, are very important for the commercial and industrial zone to the south of Vienna and have been improved to provide a very efficient service. The trains run every 15 minutes from the centre of Baden to Vienna. Today the line is very popular although it was threatened with closure on several occasions in the past. The articulated tramcar with 8 axles is 26.75 m long, has 2 engines, weighs 36 tonnes and can seat 64 passengers.
