Charting Tool A tool for a computerised Master chart (developed for Mumbai Central Division, Western Railway) IIT Bombay, Western Railway Presentation adapted from Mumbai Central Division, Western Railway Acknowledgement: Mr. S.S.Chandrayan

Master chart Scaled graphical representation of trains over a section (i.e group of stations) depicted on ‘Y’ axis for a particular duration of time interval (say 6, 8 or 24 hrs) depicted on ‘X’ axis.

Why a Computerised Master chart ? Advantages Flexibility - sections and duration can be varied Flexibility - sections and duration can be varied Replication - ‘n’ no. of copies can be made Replication - ‘n’ no. of copies can be made Modification - easier to alter or rectify data Modification - easier to alter or rectify data Moving a Train - simulations Moving a Train - simulations Portability - easier to carry Portability - easier to carry

Technical details Uses Java 2 as development platform. Input tables in MS Access Dimensions : Dimensions of axis Dimensions : Dimensions of axis Station list ( Hold Network) : Station name & distance Station list ( Hold Network) : Station name & distance Time Table Up Time Table Up Time Table Down Time Table Down Blocks :Details of block timing & stations Blocks :Details of block timing & stations Databases : Drivers or Connectivity names Databases : Drivers or Connectivity names

Output chart can be manoeuvred Section can be altered Duration of plot can be varied 24hrs, 8hrs etc. Selected groups of train can be plotted such as only Up, Down, Mail/Exp, Goods trains Chart of any size A3, A4, plotter Blocks can be displayed

Applications Addition of new services can be viewed easily Timing of selected services can be changed and impact on rest can be seen Train movement in unusual condition like accidents, rains or maintenance blocks can be viewed.
