Tirur work is slow (comparing the work done week on week -see my one month old post and new post with picture difference is minimal). and this substation has been long over due, the stretch between shornur and calicut was completed way back in March 2015. Infact only thing that was on the plot few months back was the KSEB cable which seems to have been laid earlier.
It was sheer coincidence that very next day after i tweeted about not many train running on e-loco (with these photos), few more trains moved to e-loco.
