To simulate power network of electrical railways, DigRail software has been developed by FASBA team. Investigating behavior of power network in case of changing of movable load of electrical railway and Proportionality of network and substation design, is one of main features of mentioned software.

DigRail has been based on professional studying software OPENTRACK and DIgSILENT. OPENTRACK is Sweden product that can do railways network design completely. Main disadvantage of that is simulating power network and related studies. DIgSILENT is German software which can execute 

DIgSILENT is German software which can execute  all power network studies and considering these specialized features, wide used in variety of locations and also in Iranian power network. The main disadvantage of it is Investigating behavior of power network in case of changing of movable load of electrical railways. These two software incorporated to make complete software for electrical railways studies.
