Yup. A one way trial from HWH to RNC was conducted. It was only a route trial between them taking a shorter route. As I got to know, its not for any Shatabdi exp but for a new intercity train between the two cities. The hosting zone too was surprisingly SER. The loco and coaches were of SRC as against of HWH. Maybe it's a proposed regulatory finalised in any IRTTM meeting.
