Note as of 2025: Very little monitoring data is available due to railroads transitioning to a new radio system. This system is no longer very useful but will be kept running for a while.
Rail Watch uses data from ATCS monitoring servers to create real-time maps and charts for USA Rail Traffic.
Warning: any data found on this site may be inaccurate, incorrect, missing, wrong, fake or delayed. Not to be used for life or safety critical purposes!
