Some signalling mistake @ Isivi, I saw the SM coming running on the pf after looking at the train halt abrublty. The signal was red on the main line, it didn't halt on the loop line . His facial expressions weren't positive. He had some chat over walkie talkie and went in his room, the signal became green soon . May be some mistake on his end or some TSR , but there were clearly no signs of TSR. I don't know much about signalling and don't know if automatic signalling is implemented in this section. If there's no auto signalling, clearly SM was caught napping. This is purely my observation. There could be other reasons too.. After MALM, there was no MPS run, max it was around 70kmph..
