Jvgdata STH A/B/C/S train

The object type STH(A/B/C/S train) shall be read as the “maximum speed” (STH) of A/B/C/S trains in which the driver may drive the train. The speed of a distance is signposted on metal boards along the track. Details of these boards can be found in the data product Tavlor (mainly ATC). They indicate the speed limit of the distance. If the runway is equipped with ATC systems, a certain overspeed in % may be allowed compared to signposted speed. The percentage of speed overrun is indicated in the data product overspeed %. The speed depends on the type of train to run. This applies to tracks that do not have traffic control systems ERTMS. The data product is refined from the speed-over % subdivision type and the value of Traps (mainly ATC) for the runway. The values of a route are multiplied (a bit simplified), thus giving the maximum speed of the route for the type of train. The data product is thus broken down into different train types; A, B, C and S trains with values in the order they stand. Valid values are given as x/y/z km/h. The values are rounded down to the nearest ten (some exceptions are available with values in intervals of five). An additional exception is the value of 1/1/1, which means that there is no information to calculate the speed. The data product has stretch distribution and connects to the network with reference to the nearest previous node with distance in meters to both the starting and the end of the route in the direction of the track link. The data product inherits the same position as the object type Tavla(mainly ATC).
