Amtrak's Southwest Chief leaving Hutchinson, Kansas. Time exposure of about 4 minutes at <i>f</i>/4 on ISO 400 film. This railroad crossing is shared between UP and BNSF, hence the four crossing arms. For cars not to get stuck between the tracks, one gate stays up depending on which track has a train on it.
