CEO/Founder of LOCOTSD.COM
Founder - S.T. BHAGAT

Welcome! I'm S. T. BHAGAT, the founder of locotsd.com. My journey into the world of Indian Railway began as a LOCO PILOT, sparking in me a desire to reveal the complex inner workings of locomotives and the various faults that can arise. Here I focus on making complex fault diagnosis easy, simple, and a step-to-step trouleshooting process. I hope this website helps to expand both your knowledge and mine.
