Thailand's Ministry of Transport is exploring the creation of the nation's first train-through-building, with the Red Line section between Hua Lamphong and Wongwian Yai earmarked as the potential pilot project.

The plan involves constructing a station directly through the former Merry King Department Store.

A study trip to Chongqing Municipality in China highlighted the innovative concept, exemplified by Liziba Station on Chongqing Rail Transit Line 2, which features side platforms with the track alignment and station integrated within commercial and residential buildings.

The development of railway lines and stations within buildings in Chongqing was driven by the city's dense population and limited land availability, necessitating the maximization of space efficiency.

In areas where large-scale land acquisition proves challenging, integrating infrastructure with existing buildings offers a resourceful solution.

The buildings accommodating Chongqing's through-building railway lines are specifically designed to support the rail infrastructure, rather than being standard constructions.
