What happens to train operations under a building constructed over the railroad?

When a building is constructed over a railroad, train operations typically continue as usual. This means that, in most cases, the railroad tracks remain functional and are used for regular train operations regardless of the presence of the structure above. The railroad cannot simply cease operations on the tracks unless specific agreements or considerations dictate otherwise.

The continued operation is crucial for maintaining transportation logistics and the flow of goods and services, as railroads are a vital part of the transportation infrastructure. Such arrangements may involve engineering solutions to ensure the safety and stability of both the building and the rail operations, including factors such as weight loads and vibration impacts. Therefore, the correct answer acknowledges that the railroad retains operational status beneath the building, allowing for the continued use of the tracks as they were prior to construction.
