However, following accidents on 6 March and 9 March 2001, when trolleybuses were changing from guided to unguided mode and struck adjacent overhead-wire support poles, all trolleybus operation was suspended indefinitely.
Most of the system's overhead wiring has been kept in place since the suspension that began in 2014. [6] In connection with this plan, a new Van Hool trolleybus from the Geneva trolleybus system was brought to La Chaux-de-Fonds and made a test run under the wiring there on 25 November 2021. [9]
Dual-mode (diesel-trolley) buses operated 15 September 1990 – 24 January 2005 on routes using the Downtown Seattle Transit Tunnel. The overhead wire system in the tunnel was not connected to that used by surface trolleybus services.
