KOCHI: At the frenetically busy Ernakulam south railway station on Friday evening, passengers and staff on platform 1 were in for a colourful surprise. As the Dhanbad-Alappuzha Express rolled in, they noticed that the last three compartments were covered with bright and artistically done graffiti.The tell-tale ‘Rail Hoons’ next to the graffiti left no doubt as to whose handiwork it was. Kerala, it appears, has finally arrived on the international rail map!Even as a crowd pored over the words and colour schemes with the purposefulness of seasoned exhibition-goers, the railway police were not amused. Atul Pathak, Railway Police Force inspector general, said that such offences could be treated as nuisance and the perpetrators will be charged under relevant sections of Railway Act.The Rail Hoons are internationally infamous for damaging public property, especially rolling stock, but at least on the Dhanbad-Alappuzha Express nobody was complaining. The three compartments had separate words painted on the surface amidst bright doodles. One compartment had ‘BIGCO’ written in green and white, another had ‘SANIK’ written in green and yellow with a bright red backdrop and a reference to the gang’s name, ‘HOONS’. The third compartment had SANIGRI written in bright red.“I was monitoring the metro piling works when I noticed the bright colours on the train. It was artistic and beautiful,” said Kochi Metro supervisor Ron Mathew who was supervising Metro work near south railway station.Rajiv R, a passenger who was waiting at the station, said that the graffiti actually made the trains look good. “The usual blue coloured trains covered in dust are anyway unpleasant. The artwork actually improved the train’s appearance,” he said.
