You suggestion of units being A, B & C has some merit.
Makes arranging delivery easier, As cab to rear of truck, Cs cab to front of truck.
Alternately, for delivery of the opposite end cars the truck could park with the ramp end facing the opposite direction if the orientation does matter for the road trip. I guess the logistics of how the shunts go in the depot might have an influence on the procedure. Good thing a portable ramp is being used for maximum flexibility!
I will be more interested in how things go with the centre cars which have permanent couplings that won't be as simple to handle as coupling up with a DEMU or even the previously-delivered end car of the same unit.
Good work by the road transport crews, the DPTI photos showed that there was some very tight work to be done, especially at the Seaford end.
All very well until a set or two have a collision or other misfortune. They could well finish up with a surplus of A's and two or more Cs out of service. Until the goal loop is reinstated there is no way of turning them. (somebody needs to take over from Heath) A turntable at Dry Creek would silence the Gaol Loop supporters (just).
Surely it would be cheaper to just use a crane to turn one around than to build a new turntable or rebuild an otherwise unnecessary connection from the Gaol Spur to make it a loop if that was ever a problem.
In the event of a unit needing to be formed of a mixture of different units' cars while others are under repair, it would be no hassle to reform a unit as 4016A-4016B-4003A for the time being and have internal systems simply refer to it as 4016 for operational purposes while still tracking the individual cars for maintenance records. It's a small fleet of only 22 units in total so the maintenance crews should be able to cope with the occasional anomaly.
It would be of more more interest to spotters and haulage/mileage logging enthusiasts than anything else! If you read through various UK forums you'll see there is a great amount of hysterical chatter when a unit is formed of cars from two different units, or when intermediate cars are redistributed to consolidate a fleet into a smaller number of longer units.
