UIC or UK Railway Loading

Vehicles​

  • UIC 71/RU axles – locomotive axles for RU loading to BD37. These are the same as the axles for UIC 71. Note that the UDL to be applied either side of these axles is not included.
  • SW/0 – works train, two 15m long UDLs 133kN/m separated by 5.3m gap.
  • SW/2 – works train, two 25m long UDLs 150kN/m separated by 7m gap.

Path loads​

  • RL – UDL [50kN/m] + KEL [200kN]
  • UIC71/RU – 80kN/m UDL, UIC71/RU axles, 3.2m exclusion length

These loads will normally be applied to Track Paths with the default standard gauge of 1.435m. Effects of lurching and centrifugal effects can be modelled using the Left Rail Factor when specifying the Track Path.

Note that dynamic factors are not included in the above loads and need to be applied separately.
