Which probably isn't ideal.
Let's assume it is starting each day leaving the depot with 100%:
- 9.6 miles dead to CLS according to Google.
- Approx 10 miles between CLS and NCL. It does this 7 times (06:50, 07:40, 08:32, 09:30, 10:24, 11:20, 12:14) before the Brandon trip, for a total of 70 miles.
- Approx 20 miles from NCL to Brandon, it does this round trip once so that's 40 miles.
- It then does another CLS round trip (16:32, 17:29), and one last trip down to CLS (18:24), for another 30 miles.
- Then another 9.6 miles dead back to Riverside.
That's an approximate 160 miles per day on that board. If we say it does come back nearer to 30% remaining than 25%, that means 160 miles is 70% of its fully charged range. That gives an approximate 230 mile range on a 100% battery.
If you look at what 6315 did today, it ran dead to CLS to start (9.6 miles). It then did a trip to Durham from CLS (6.7 miles), a trip to Newcastle (17 miles), a Brandon round trip (40 miles), 2x CLS round trips (40 miles), another Brandon round trip (40 miles), a CLS round trip (20 miles), a Durham round trip (34 miles), and a dead run back to Riverside to finish (approx 5 miles). That's a total of 213 miles, and it isn't even a midnight finish or the first bus out of the yard in the morning. You're talking 17 miles to play with, and as those batteries start to degrade that's not an awful lot of wiggle room.
That's even before you consider that the range will take a bigger hit on the higher speed sections of route between CLS and Durham, which it would be required to do more often on most other boards.
