SWR should think of linking Hosur line to Jolarpet line -- Heelalige/ Bellandur to Whitefield/ Hoodi. This will give tremendous flexibility to run more trains. Long distance trains like LTT CBE, Kongu can take that line to travel via KJM and to avoid loco reversal. Few more trains like CST NCJ/ TVC can also run via Hosur if such a link is done.
Yes, a by-pass link from Hosur line to Ynk line, will reduce time and loco reversal.
