C.2.2: Transition Curves - 2

3 Transition from Circular Curve to Circular Curve A transition from a curve of radius R 1 to a similar flexure curve of radius R 2 may be calculated by using theequivalent radius R E , where:

RE =

and R 1 > R 2 in place of R in the transition formula.

Reverse transitions must have a constant rate of change ofcurvature. Cants, when rounded off, may not necessarily givea constant rate of change of cant but, ideally, levels shouldbe set out as shown in the diagram below.Refer to sheet C.2.1 for details of the form of the transition

This form of transition is used in the NR60 design of switches as shown on sheets A.1.2 & A.3.3This form of transition is also used in normal Hallade curve realignment work.

6 Bloss Transition CurvesThe Bloss transition is a geometric form of transition in which the fourth differential of acceleration is set at zero, ascompared with the second differential for a clothoid spiral. The general equation to the curve is:

y =

Hence the slope of the curve, , at any point is given by: tan =

With the special case of the slope at the heel of the transition, , being given by: tan =

The local curvature (reciprocal of radius) at any point is given by:

Shift on transition, S = Versine at any point is given by:

NOTES1. Crossing angles shown are for CEN56E1 Vertical S & C design, at 1432mm gauge.2. See Sheet C.3.2 for NR60 Inclined S & C design3. The use of the last column requires the main line to be straight, and assumes that the centreline of the branch

line is parallel at the common crossing intersection point (I.P.).4. For details of turnout lead lengths, and toe to IP, see sheet A.2.1 and A.3.1.5. N/A - not applicable - swing nose required.

Follow-on Switches

NOTES1. The diagrams show typical bearer extensions for point motors. The Network Rail Signal Engineer may require

particular alterations.2. Switches fitted with Clamp Lock mechanisms will not normally require extended bearers.3. (a) These bearers may be extended in the opposite direction by agreement.

(b) For second and subsequent drive positions where the rod run is positioned on the bearer ends.(c) Extended additionally for the detector.(d) The minimum opening between running edges is to be:

For EP motor worked switches: 1067mmFor Clamp Lock operated switches: 385mm

(e) The standard length of concrete bearer for point motors is 3600mm.4. Sheet re-numbered in June 2008 (was D.6.3) - data unchanged.

Network Rail


D.7.1: Trap Points and Vehicle Retardation

Unless other arrangements are in place which fulfil the same purpose, trap points are required to protect passengerlines from unauthorised train movements from:

Freight-only lines and sidings;

Crossing loops on single lines where the overlap beyond the protecting signal is substandard or where the lineis worked by a non-token method; Passenger loops, bay and loop platform lines; Converging freight-only lines where the consequence of an overrun might foul a passenger line.

Any trap point provided for the protection of a passenger line shall be of the double switch type and shall have theappropriate switch rail extended to form a throw-off, which will enable the vehicle running through the points to bedeflected away from the passenger line being protected. In situations where the trap is close to the fouling point ofthe main line, the turnout rails should be further extended to enable the derailed vehicle to be guided away from therunning line. In some situations a full lead may be required.The secondary risk of consequence to the derailed vehicles themselves shall be considered in the siting and design

of trap points. Derailed vehicles should remain upright wherever possible and be deflected away from hazards andobstructions such as overhead line structures, adjacent highways, signals and buildings.

Trap points in sidings may be formed using AV switches, provided that they are not installed in CWR. In running lines, strengthened traps shall be formed of BV or BVS switches, except where the PSR on the

approach is greater than 40mph; in which case CV or CVS switches shall be used NR60C leads may be used as trap points, but their use should be confined to locations where it is not possible

to install Vertical traps.

In particular locations; at the approach to swing or moveable bridges, or at stations where vehicles are leftunattended at gradients steeper than 1 in 500, it may be necessary to consider the provision of some means of

progressively slowing vehicles to a stand.The design chosen will depend on a risk assessment and the ability of the design to stop the type of traffic using theroute. the installation and outcome of a TPWS intervention should be taken into account at the design stage andconsidered in the risk assessment.These retardation arrangements include Friction Buffer Stops, Retarder Trap Points (see sheet D.7.2), spring ormechanical retarders and (where appropriate) Sand Drags (see sheet D.7.3).The effectiveness of friction buffer stops can be accurately modelled and designed to suit the traffic and location.The effectiveness of sand drags depends on the type of material used, its depth and compaction, whether it is wet ordry, and the type, weight and speed of the vehicles involved. Sand drags are best suited to retard trains running atlow speed; typically the exits from bay platforms, loops, approaching buffer stops in terminal or bay platforms, andprotecting running lines from shunt movements.

Loose, uncompacted blanketing sand (to Network Rail Specification NR/SP/TRK/033) to a depth of 450mm aboverail level is recommended for new sand drags.

D.8.1: Level Crossing Surface Systems - 1

Definition of a level crossing surface system: An installation, including the associated support system, providing a continuation of the road surface to enableroad vehicles to cross the railway on the level. The term does not include cattle-cum-trespass guards,signalling devices, signs, barriers and the track system.

Table 1:Application of Proprietary Systems by Crossing Type:

NOTES1. Must not be used on routes equipped with Vaughan Harmon Track Circuits2. Available for flat bottom rail sections only3. Not recommended at Accommodation/Farm crossings on track circuited lines4. STRAIL will be superseded by STRAIL 20055. Only permitted where timber sleepered track exists in track categories 4 - 66. In accordance with NR/L2/RVE/0007 Specification for on and off tracking of Road-Rail Vehicles (RRV)7. Not in running lines

E.5.1: CEN56E1 Vertical S&C - Obtuse Crossings - 1 in 4.75 to 1 in 8

Table of Timber Spacings and Baseplates for Fabricated Crossings

NOTES1. Fixed obtuse crossings shall not be used where

a) the line speed exceeds 90 mph on jointed track or 105 mph on fully welded track;b) the crossing angle is flatter than 1 in 7.5, exceptionally 1 in 8;c) the radius of either track is sharper than the limiting radii shown in sheet A.5.1;d) a negative cant occurs on either track through the crossing.In any of these cases, switch diamonds shall be specified.2. Fabricated obtuse crossings shall not be used where the line speed exceeds 75mph.3. All dimensions are in millimetres.4. Rail lengths:

Wing rails 5690 for all angles.Check rails 5690 for all angles.Point rails Length depends upon the adjacent common crossings, see table, below, whichgives point rail lengths measured from the nose.

Combined point/wing rails, indicated in the table as special are to be specifically detailed and manufactured.
