Route 614: University Bus (Uno): 252 (YX17NRE) ADL E40D/ ADL Enviro400MMC City

A brief interlude with a trek up and down from Hertfordshire with some motorway-ing MMC action, into the city with Uno's MMC City YX17NRE
New in July 2017, YX17NRE was new to Hertfordshire independent Uno (University Bus), comprising one of 6 ADL Enviro400MMC Cities for "Comet" routes 614 & 644, displacing Optare Olympus bodied Scania N230s and Mercedes-Benz O530 Citaros from the route, all of which are based at their main depot at Gypsy Moth Avenue, Hatfield.
Our journey comprises a run on the titular "Comet" route 614, which runs from Hatfield Station to Queensbury Station via Hatfield Business Park, de Havilland Campus, The Galleria, University of Hertfordshire, down the M1, Barnet, Arkley, Edgware & Burnt Oak. The 614 was one of Uno's first routes they operated if memory serves me correctly.
252 is powered by a Euro 6 Cummins ISB6.7 engine coupled to a Voith DIWA D864.4 4-speed automatic gearbox.
Start: Hatfield, The Forum
Finish: Barnet, The Spires Shopping Centre
