PURPOSE: To select whether the stop line of a desired train at a desired station is drawn or not freely by providing a means to decide whether a stop line at a station is drawn or not depending on a stop line condition data including a stop line condition data whether a stop line at a desired station is drawn or not as a part of the train data.

CONSTITUTION: An input interface 6 exercises a mediation of the data between an input device (mouth K/R) 5 and a computer 10 such as an EWS, and a deciding means 7 decides the drawing/nondrawing of a stop line, while an output interface 8 exercises a mediation between the computer 10 and an output device 9, and the output device 9 consists of a plotter and a printer to output a stop line condition data 11 and the like. A stop line condition data 11 can be set to a desired train and a desired station from the input device 5. When the drawing is carried out at stations A, D, and E, but not carried out at stations B and C, for example, a train line 12 the stop line condition data is reflected can draw a stop line only at the stations A, D, and E, and from the starting time 13 at the station A to the arrival time 14 at the station D is joined with a straight line.
