</div>In my experience, railway data in TIGER is much less likely to be up<br>
to date than road data, presumably because census workers need to visit<br>
people that live along roads, but railways are just convenient reference<br>
points. There are railroad rights-of-way in Maryland that were<br>
abandoned in the 1970s, complete with pulling up the rails, but were<br>
still listed as active in TIGER.<br>
<div><div></div></div></blockquote><br><div><br>The problem is compounded by the fact that railway companies treat their data as proprietary. Census frequently has to resort to secondary sources for accurate and up-to-date rail data. Sometimes they rely on Dept of Transportation for this data, but there is often a lag and differing views depending on mission as to what constitutes 'active', 'abandoned', 'ownership', etc.<br>
