Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Central Secretariat or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,Slovenia, Spain, Sweden, Switzerland and United Kingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

Key 1 Actuation force 2 Displacement Figure 1 — Actuation forces 3.3 Geometrical parameters 3.3.1 stud gap, dstud gap between the stud supporting surface and the corresponding surface of the moveable part (i.e. switch rail, point rail, wing rail)

Key 1 dgap (either dgap1 or dgap2) 2 dtoe Figure 2 — Gap of closed switch rail

Key 1 dgap or dtoe Figure 3 — Maximum gap of closed switch rail 3.3.5 foot clearance, dfoot distance between the foot of the switch rail and the nearest part of the stock rail or any other component (bolt, heaters etc.) fixed to it, ensuring clearance between both is maintained (see Figure 4) For additional equipment (e.g. heaters, cable connections) this clearance has to be maintained. Longitudinal displacements are taken into account.
Key 1 dfoot Figure 4 — Foot clearance 3.3.6 toe movement, fp movement of the toe, when moved by the actuator. It is the distance between open and closed position at the toe (see Figure 5)

Key 1 Actuation position Figure 5 — Opening and flangeway 3.3.7 opening at the drive position, fd movement of the switch rail at the drive position. This movement is less than the toe movement (see also Figure 5) 3.3.8 neutral switch rail position, fN position of the switch rail, if no external effort is applied to it. The neutral position is verified at the first drive position. The same principle applies to crossings with moveable parts 3.3.9 actuator movement, fa movement of the actuator rod 3.3.10 minimum flangeway, ff see EN 13232-1:2003, 7.4.6 and Figure 59. (See also Figure 5.) This dimension is measured at the gauge reference plane 3.3.11 track gauge, G see EN 13232-1:2003, 2.11 and Figure 5. (See also Figure 6.)
