Ladder Track is a type of railway track in which the track is laid on longitudinal supports with transverse connections holding the two rails at the correct gauge distance. Modern ladder track can be considered a development of baulk road which supported rails on longitudinal wooden sleepers. Synonyms include Longitudinal Beam Track.

Early forms of ladder track include Baulk road, ladder type track has also be used historically on bridges lacking ballast, and in situations requiring good drainage or ease of maintenance such as stations. Research into longitudinal sleepers took place in Japan, Russia and France in the mid 20th Century. In the late 20th century, interest in ladder type tracks increased due to its potential for lower cost and lower maintenance railways, as well as increased stability benefits over sleepered track.

In general, ladder track produces lower pressures on the road bed: both the maximum pressure and the amplitude of pressure pulses are smaller than transverse sleepered track, which can reduce maintenance costs in ballasted systems. An additional benefit in ballasted ladder track is increased resistance to ballast wash out and other forms of ballast degradation due the addition longitudinal support and rigidity in ladder track.; the same structural rigidity also adds to buckling resistance.
