Marshalling yard

A big show can attract hundreds of trucks in a two-day window against a dock that handles a fraction of that at once, and the marshalling yard is what turns that maths into a queue instead of a gridlock. Drivers check in at the yard, present paperwork, receive a sequence number, and wait until the dock team calls them forward — usually by radio or text — so the dock never has idle bays or blocked approaches. Organizers or their general service contractor arrange the yard, and in dense cities it's often a rented lot some distance away, with real costs for land, staffing, and shuttle time. Commercially, a well-run yard is invisible; a badly run one produces drivers abandoning slots, freight arriving out of sequence, and exhibitors staring at empty booths the evening before opening. It can also be a licensing condition — many cities require a traffic plan that keeps trucks off surrounding streets. The common mistake is under-communicating with drivers: check-in procedures published only in the exhibitor manual never reach the subcontracted haulier actually behind the wheel. One honest nuance: yard waiting time is unpaid pain for drivers, and shows that habitually hold trucks for hours get quietly deprioritized by carriers next year.
