These three shapes provide the basis for numerous other permutations in rail profile.

At first the Rail profile protruded above street level, causing accidents and problems for pedestrians.

The result was a special - lightweight - Bavarian Lokalbahn rail profile.

They are most effectively used for cutting railroad rails, because the saw blade enters optimally into the rail profile.

A longitudinal channel formed in a hot rolled rail profile such as a grooved rail.

The track usually consists of two Rail profile, but might also be a monorail or magnetic levitation train guideway.

By 1840 there was a mixture of bridge rails, single parallel and double parallel rails (See Rail profile).

Alternatively, the word can refer to the highest part of a rail profile, on the top surface of which the wheels of the rolling stock run.

The rail profile was invented in 1849 by W.H.Barlow, engineer of the Midland Railway.

This ratio is accomplished by matching the wheelset with the appropriate rail profile to achieve the L/V ratio desired.

The rail profile is the cross sectional shape of a railway rail, perpendicular to the length of the rail.

The vertical alignment (or profile in the United States, but not to be confused with rail profile) is the surface uniformity in the vertical plane.

The rail profiles were upgraded to 49 kilograms per meter (78 lb/yd), were continuously welded and the gravel ballast was replaced with crushed stone.

The two platform tracks are built as conventional ballasted track with S54 rail profile and can also serve as passing loops to allow trains with higher priority to overtake.

A further enhancement to the rail profile produced the 113A section which was the universal standard until about 1998; detail improvements to the sleepers and ballast profile completed the picture and the general form of the track had stabilised.

On a rail profile map the "final" 7 miles from Mendham to Watnong (2 miles from Morristown) appears as a gently downhill ride into the county seat of Morris County, New Jersey.

The rails are laid using a UIC 60 kg/metre rail profile, with electrically welded rails attached to 2.30 metres-long prestressed reinforced concrete sleepers, spaced 60 cm apart with Pandrol clips.

Another form of rail, the rail profile, was first used by William Jessop on a line which was opened as part of the Charnwood Forest Canal between Loughborough and Nanpantan in Leicestershire in 1789 .

However, on delivery of both scrap rail and rolling stock, Woodham's found that commercially it was easier to both comply with the contract terms and conditions and turn a profit if they concentrated on the easier to scrap rail profile and rolling stock.

The introduction of rolled rail profiles in the 1820s such as the single flanged T parallel rail and later double flanged T parallel rail required the use of chairs, keys to hold the rail, and bolts or spikes to fix the chair.
