E40LFR 800 Which is the prototype bus for the trackless trolley order is now in revenue service. The bus was originally delivered to SEPTA back in June 2007 for testing out Frankford but returned to New Flyer to be a control vehicle while 801-837 were constructed. 800 returned to SEPTA property after some modifications in late 2008 but was used to debug problems with the rest of the fleet. This unit was spotted in service for the first time on route 66 today.
