The train start to descend sharply after Lonavala till Karjat.
Hence breakers are attached at Lonavala, to keep control when descending..
Khandala ghat technical halt might be a break testing spot (not 100% sure).
please wait...Translate to EnglishThe train starts going downhill real fast after Lonavala till Karjat.
So they put these brakes on at Lonavala, to keep things under control when going downhill.
It's possible they might take a break in Khandala ghat to test the brakes (not entirely sure though).
