5.3.2 Steps at corners of shunting powered units
These steps apply to shunting pOwered units that are exclusively or mainly intended for shunting purposes.
At each of the four corners of the underframe a step enabling at least one member of the staff to stand shall be provided, This step can be either the lower rung of the steps fo gaining access to the transverse platform or a recess embodying a step.
The lowest rung of the step shall be located at the lowest height above rail level compatible with the gauge limit, not higher than 600 mm but preferably be lower than 560 mm, The positioning of this rung shall ensure the required space above steps as defined in 6,2.2. Figure 3. The unobstructed surface of this rung shall be at least 500 mm long in the running direction and at least 300 mm deep transversely.
The vertical spacing of the rungs shall not exceed 325 mm.
5.4 Handralls
5.4.1 Shunter handrail
One shunter handrail shall be located al each headsiock under each buffer. These shall be at least 260 mm long and be situated at a lateral distance of between 500 mm and 750 mm for either side of the vehicle centre line.
The minimum clearance between the handrails and any part of the vehicle should be preferably 100mm but shall be at least 50 mm. The minimum dimensions and the positions for the shunter handrail are defined In Figure 1.
The shunter handrail shall be made of round bar steel with a diameter of miii. 20 mm to max. 35 mm and the material strength shall be as a minimum that of EN 10025-2, grade S235. Such a design fulfils the load requirements of Clause 4 without further assessment.
Olher materials or designs for the shunter handrail are permissible it they fulfil the strenglh and dimension requirements given in Clause 4.
5.4.2 Handralls corresponding to shunter’s stand
The handrails corresponding to the shunter’s stand are those of the general case in EN 16116-2.
These handrails shall be made of round bar steel with a minimum diameter of 20 mm or of steel tube with a
minimum external diameter of 30 mm and a minimum wall thickness of 2 mm. The material strength shall be
as a minimum that of EN 10025-2, grade S235. Such a design fulfils the load requirements of Clause 4.
Other materials for these hancirails are permissible if they fulfil the strength requirements given in Clause 4.
5.4.3 Handralis for steps at corners of shuntIng powered units
All steps as descnbed in 5.3.2 shall be provided with handrails at both sides. They shall reach down to at least 1 200 mm above rail level and shall continue to a distance of at least 1 200 mm above the highest rung of the step.
These handrails shal have an external diameter of 25 mm to 35 mm.
The clearance around these handralls shall be at least 60 mm.
5.5 Transverse platform for shunting powered units
Access steps to the transverse platform shall be according to 5.3.2. The width of free space of the platform at guard rail level shall not be less than 500 mm, and at bottom level not be less than 400 mm.
The outside of the transverse platform shall be provided, over the whole frontal width of the powered unit, with a guard rail at least 1100 mm high. designed with a view to safeguarding staff against falling on to the track. II the guard consists of a handrail and intermediate honzorital bars, the height of the lowest horizontal bar above the floor shall not exceed 350 mm and vertical distances between horizontal bars shall not exceed 500 mm. If the guard includes a bottom rad and an intermediate horizontal bar, the latter should be located equidistant between the bottom rail and the guard rail.
The surface of the platform shall be slip resistant according to Clause 4.
6 Reserved spaces
6.1 General
To ensure sate working conditions for the shunting staff It Is necessary to define free spaces which are needed during coupling and uncoupling of screw couplings and for enabling temporary travel outside the vehicle for staff during shunting.
