Gour Express: আমের শহর মালদা থেকে রোজ যায় শিয়ালদা - Joydeep Roy

Does anybody know how goods trains are scheduled in Indian Railways? I'm pretty sure there are no specific arr/dep timings, so do they get scheduled whenever there's a gap between two passenger trains? Do they ever get higher priority than passenger trains? In really busy sections like SBC-MAS where there are 18-20 trains in a 24-hr period, doesn't it become nearly impossible to squeeze in goods trains? Does anybody know if Indian Railways uses a computerized system for scheduling goods trains?
