In a model railroad let's say ho scale for example. We have scaled everything down to 1:87. That allows time to stay the same as realtime. I'll try to explain, if we have an ho scale car and it is traveling at a scaled 50 kmh the it will take that car the same amount of time to travel a scaled km as it does for us to travel a realtime km. In other words their time is realtime too. If we didn't scale down they would be moving around in very fast motion to get to the end of a realtime km.
