To replace EN 15746-1:2020, 5.1, machines do not have to comply with geometric limits requirements stated. The geometric parameter of the track of the urban rail on which the machine is intended to travel shall be requested from the Urban Rail Manager. The manufacturer shall state in the instruction handbook the system(s) on which the machine is intended to operate.
4.2.3 Gauge, EN 15746-1:2020, 5.2.1
To replace lN 15746-1:2020,5.2.1. machines do not have to comply with gauging requirements stated.

EN 15746-1:2020, 5.2.2 is applicable except that moveable parts and assemblies do not need to be stowed and secured. It is sufficient, that the transport position of working equipment that is able to foul the kinematic envelope shall be clearly recognizable or displayed to the driver/operator.
4.2.5 Working limit, EN 15746-1:2020, 5.2.3
Where EN 15746-1:2020, 5.2.3 refers to EN 14033-2:2017, 5.3.2, machines need not comply with this working limit, or the 1 300 mm revolving superstructure limitation. The limits for the urban rail on which the machine is intended to work shall be requested from the Urban Rail Manager. The manufacturer shall state in the instruction handbook the system(s) on which the machine is intended to operate.
4.2.6 Lateral limit exceedance, EN 15746-1:2020, 5.2.4
Machines do not need to comply with EN 15746-1:2020, 5.2.4.

Where EN 15746-1:2020, 5.2.5.2 refers to EN 14033-2:2017, Annex D, machines do not have to comply with this working limit. The limits for the urban rail on which the machine is intended to work shall be requested from the Urban Rail Manager. The manufacturer shall state in the instruction handbook the system(s) on which the machine is intended to operate.
4.2.8 Working limit, EN 15746-1:2020, 5.2.6
Where EN 15746-1:2020, 5.2.6 refers to maximum work position heights shown in Annex A, machines do not have to comply with this limit. The limit for the urban rail on which the machine is intended to work is derived from the overhead wire height, which shall be requested from the Urban Rail Manager. The manufacturer shall state in the instruction handbook the system(s) on which the machine is intended to operate.BS EN 15746-4 pdf download.
