This track was intended to be an express track, but engineering studies completed after the work started indicated that the vibration of trains passing over the stations would be too severe and would literally shake the stations apart.
This track was intended to be an express track, with work beginning on the proposed express track in the late 1960s. However, engineering studies completed after the work started indicated that the vibration of trains passing over the stations would be too severe and would literally shake the stations apart.
