SINGAPORE - Ever wondered how MRT tunnels are built? The Land Transport Authority is holding a number of rail road shows to give commuters an idea of what it takes to build those MRT tunnels that commuters travel through every day.

On display will be a miniature version of the two-storey high, 50-tonne tunnel boring machine that grinds through rock and dirt to dig tunnels.

The LTA's rail road show will run from November to January at Parkway Parade, Thomson Plaza, Bedok Mall, and Katong I12. The show will have exhibits that tell the story of how Singapore's rail lines have expanded. Visitors can also learn about rail expansion plans and get to see MRT station layouts.

On the weekends, visitors can take part in games and quizzes to learn more about what it takes to build a rail line.

Roving exhibits on new MRT lines will also be on display at public libraries from January to May next year.
