The following are the principal requirements of an ideal permanent way or of a good railway track permanent way should be correct and uniform proper level in straight portion.
i. The gauge of the permanent way should be correct and uniform.
ii. The rail should be in proper level in straight portion. The proper amount of superelevation should be provided to the outer rail above the inner rail on a curved portion of the track.
iii. The permanent way should be sufficiently strong against lateral forces. iv. The curves, provided in the track, should be properly designed. v. An even and uniform gradient should be provided throughout the length of the track.
vi. The tractive resistance of the track should be minimum.
vii. The design of the permanent way should be such that the load of the train is uniformly distributed on both the rails so as to prevent unequal settlement of the track.
viii. All the components parts such as rails, sleepers, ballast, fixtures, and fastenings, etc. should satisfy the design requirements.
ix. All the points and crossings, laid in a permanent way, should be properly designed and carefully constructed.
x. It should be provided with proper drainage facilities so as to drain off the rain water quickly away from the track.
xi. It should be provided with safe and strong bridges coming in the alignment of the track. xii. It should be so constructed that repairs and renewals of any of its portion can be carried out without any difficulty
