(20 May 2014, 5:00 pm)AIG20 wrote So, I guess two gas buses will be delivered per day (Monday to Friday). However, how do the drivers who deliver the vehicles get back home?

That's how it usually works for Optare and Wrights - as I said yesterday - but cumbria0902150 said it was originally down as Sunderland receiving five per week, so ADL may work slightly differently.
Must be said that, unless those gas buses seen today arrived late last night, we didn't see Monday's delivery.

I believe the usual procedure is for the drivers of the vehicles to get the train back to where they've come from (where appropriate)? I've seen the delivery drivers being escorted out of GNE's Saltmeadows Road depot in an employee's car and can only assume the employee was taking them to the train station... A built-in cost that the operator will no doubt pay as a cost for the vehicle.
