Railway Engineering Insights
Join me as we discuss various railway engineering topics with examples. We have tried to use basic math & physics to derive various standard formulas available in IECs, IEEEs and ENs. These lectures will support you in understanding electrical concepts behind railway engineering and make you love your work more than ever.
Information provided in my videos is for educational purpose only.
Cheers!
