The logo seen on 30341 was the first logo designed for P7s and can be seen mostly on older P7s of RPM but I think 30541 has this logo(not sure as I spotted it at speed). There is another type of logo as you can see on 30350 in
/blog/post/2348079 and another on 30479(aka Thangam, the 50th P7 of RPM) in
/blog/post/1961718 though both are same but in different colours with "SR Royapuram Electric Loco Shed" markings in Hindi and English mostly found on later ones.
