Getting the sense from my occasional railfan observations of Guilford train ops. that crews are being driven to just about any train that they're needed on from their designated OD locations. Example-LA-1, the Lawrence local crew, was taxied from Lawrence to Gardner to take a loaded coal train to Bow recently. Today I saw an eastbound leave Ayer called AYPO, but somehow I got the feeling that train could just as well tie down at Wamesit and get re-crewed by a MOPO crew from East Deerfield. Anyway it sounds as if the manpower situation on GRS is requiring a lot of driving miles. Also, train symbols are just paper, not reality, witness WARJ going nowhere near Rotterdam Jct by taking a left at Ayer with CSX power to Worcester. 
Jonelle; I've thought about GRS using their own vehicles and employees to "cab" crews,but;1)It's cheaper to use taxi firms. Most of the cabs they use are "rent a wrecks" and small operations,who can use the small,but steady income GRS provides(when they finally send a check!)20GRS employees would be "on call" for this taxi service and their hourly wages are far more than "cabbies". 3)GRS has a fleet of vehicles that are not very dependable and this extends to PanAm! Wife and I saw an older PanAM Explorer in Kittery a while ago that sounded horrible:Not a good "ad" for the mechanical rebilabity of the planes we said! I know the SLR will sometimes use taxis,but they have a company car based at the engine facility in Auburn(ME) for 394s crew to take to the motel for their rest and to return in when they report for the return leg as 393. When 394 runs out of hours,somewhere west of Auburn,one of the local switcher crews will take the car and meet the train,giving the car to 394s crew to go straight to the motel,and the local switcher crew will bring the train "in" to Auburn. Usually this is either 516 or 513s crew. GRS crews staying at HoJos Motel in S.Portland(ME) will have the motel van pick them up and drop em off at Rigby Yard,less than a mile and 1/2 from the motel.
