| 85-90 drivers is the usual maximum at NHIS. That permits 4 run groups, each allotted 4 runs of about 25 minutes.
That leaves about 20 cars per group, again ideal IMO. More cars than that and it gets too crowded with too main "trains". With only 10-12 cars per group it gets too lonely out there, and starts to feel like the Trans-Lab in February sometimes! |
