BANGKOK — West Japan Railway Co.'s long-distance sleeper Blue Trains, the last of which were retired in March due to lack of passengers, are back on track in Thailand.

State Railway of Thailand, plagued by financial difficulties, has been receiving Blue Train and other cars from JR West free of charge and adapting them to the country's narrower gauge.

According to the national railway, Blue Train cars are only in use on the Trang-Bangkok route, and on special trains during the tourist season.
