Stereo file of Newcastle's Railway Bridge. The left channel is a contact-mic attached to the bridge itself. The right channel is an ambient mic. Internal and external sounds. The 'ground hum' that appears after the train passes isn't an equipment failure. These hums appeared regularly each time before and after a train passed over.
