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.
