As you might know, a 'service' of rally cars starts at a predefined time and has to be finished within prescribed minutes. Each rally car will be serviced usually at 3 times in a day; in the morning, almost at noon and in the evening. 'Service Park' is where the mechanics do their service. You can see WR cars in front of you there.
If you want too see WR cars and drivers within your arm's reach, you should visit a remote service. Some of the WRC events use the system. Organizer adopts remote service when the special stages are so far from the service park that crews cannot easily come back in the daytime. At a remote service, only four persons; two mechanics, the driver and the co-driver can touch the car. Also they can use only on-vehicle tools and spare parts/tires. The period of the time of a remote service is always shorter than a service in Service Park. So rally cars must wait until the night for a heavy maintenance. Crews have to take much care of their car during special stages when the remote service is set so that they can avoid retirement.
The Swedish Rally made maximum use of the remote service system. The midday service was held away from Karlstad throughout the rally. So, Sunne in the Day1 and Hagfors in the Day2 and Day3 took an important role in the whole event. They were another host town of the Swedish Rally.
For your information, there was no Service Park during the rally in the past. Service cars with full of mechanics, tools and spare parts used to wait rally cars near special stages and the mechanics used to fix the car everywhere they like. Things have changed!
