| Trolleybus deliveries delayed filed on: 28.02.2013 (28th Feb 2013) The availability of the new double-articulated trolleybuses 78-89 has been somewhat problematic during their first months. The reason for this was that, in contrast to the earlier batch (61-77) which has auxiliary diesel motors for moving away from the wires, the new units had lithium batteries, the charging cuits of which have not always behaved as expected. Consequently, the subsequent delivery of Swisstrolley4 single-articulated buses has been delayed. The first unit should have been delivered at the end of last year but so far none have yet been seen in Zürich.
