Two railway employees have been placed under suspension for allegedly causing delay in the movement of Congress chief Sonia Gandhi's cavalcade during her visit to Rae-Bareli. Authorities took action against the employees, one of them a gateman, for not being present at a rail crossing which was closed, when the UPA chairperson's entourage reached there onTuesday. Official sources said, Mrs Gandhi's cavalcade was stuck midway at a railway crossing of Jalalpur Ghai station and the gateman was missing. The Congress chief is on a visit to her Parliamentary constituency. <br/>
