A cloudy morning suddenly wakes up to a beam of sunlight, as the #893SR Tanjavur-Tiruchchirapalli DMU makes its appearance... Note the unused meter gauge line on the right, which was once trodden by such trains as the Cholan express and Rameswaram expresses .... Location: Ponmalai - right at the junction where the lines to Chennai and Tanjavur diverge. (Manohar Natarajan)
