Meter load

The meter load in tons per meter (t / m) (incorrectly sometimes also called weight per meter ) is a parameter for assessing whether certain rail vehicles can be used on certain railway lines. Together with the axle load, it determines the route class .

The meter load of a rail vehicle is calculated as follows: ${\displaystyle ML}$

${\displaystyle ML={\frac {m_{ges}}{LuP}}={\frac {m_{Fzg}+m_{Ldg}}{LuP}}}$

With

• the total mass of the vehicle ${\displaystyle m_{ges}}$
  • the net mass of the vehicle ${\displaystyle m_{Fzg}}$
  • the mass of the cargo ${\displaystyle m_{Ldg}}$
• the length over buffers . ${\displaystyle LuP}$

Compliance with the meter load is particularly important for bridges , as they have a maximum permissible load that must not be exceeded. It can happen that a bridge with an exceeded load per meter may be used as an exceptional consignment (usually with speed restrictions) if other cars are lined up in front of and behind the respective wagon whose weight per meter is significantly lower than the permitted, because this is the permissible traffic load of the Bridge is not crossed.

The term is used analogously for road vehicles (especially in connection with the loading of bridges by trucks ) (see EuroCombi ).
