BANGKOK Mass Transit System (BTS) has awarded contracts worth a total of Baht 10.9bn ($US 305m) for two fleets of metro trains. Siemens will supply 22 four-car Inspirosets while CRRC Changchun Railway Vehicles, China, will supply a further 24 four-car trains.
To accommodate increasing demand and network extensions, Bangkok Mass Transit System (BTS) engaged in a project to upgrade its track-circuit based signalling system to communications-based train control (CBTC). Mr L Y Lam, advisor to BTS, and Dr Chaisak Srisethanil, BTS' project and engineering director, chart the evolution and highlight the major challenges of this innovative project.
Bangkok is pushing ahead with several projects to improve its rapid transit infrastructure. But with past schemes suffering from delays due to political wrangling, and as another political crisis grips Thailand, Kevin Smith assesses the current state of play for these undertakings.
