The Tamil Nadu State Transport Corporation has started the operation of conductor-less buses between Trichy and Salem. While five conductor-less buses were being operated since Friday, four more were brought into service on Saturday. The introduction of the service has proved an instant hit as several passengers preferred it as the travel duration comes down by nearly an hour. The buses reach the destination either way in three hours, which is at least 45 minutes lesser than a normal service. The buses will not halt anywhere between the two cities. The fares are same and hence there is good patronage. The conductor-less services are also expected to improve efficiency and reduce operational costs. According to the officials, 100 new buses would be inducted into the TNSTC fleet in Trichy region during the current financial year.
