with holding down brackets without increasing the number <strong>of</strong> securing points on the wagons,
this problem could be solved.
It is concluded that it must be more economic to put restrictions on the wave height in which
the train ferries may operate than to equip all freight wagons with new stronger securing
fittings <strong>for</strong> ferry transport in the Baltic Sea. Future wagons equipped with holding down
brackets will allow <strong>for</strong> a revision <strong>of</strong> these restrictions, as older wagons are taken out <strong>of</strong> use.
If the wagons are equipped with holding down brackets and the ships are equipped with
securing fittings maximum 1.5 meters apart in the longitudinal direction, each lashing could
take up a <strong>for</strong>ce <strong>of</strong> 80 kN. Such an arrangement would allow most <strong>of</strong> the train ferries to operate
in wave heights up to 4 meters.
• RECOMMENDATION
Based on the results from the jvgRASLA project, the following is recommended:
1. To establish new realistic general acceleration requirements that also are allowed to be
used as a base <strong>for</strong> design <strong>of</strong> cargo securing arrangements <strong>for</strong> rail transports.
2. It should be possible to per<strong>for</strong>m tests <strong>of</strong> loading methods <strong>for</strong> sideways accelerations in the
same way and <strong>for</strong> the same <strong>for</strong>ces as <strong>for</strong> road transports. Special consideration must,
however, be taken to the vibrations that occur in a railway wagon.
3. To establish harmonised realistic strength demands on sides, ends and partition walls <strong>of</strong>
railway wagons enabling rational cargo stowage and securing in the wagons. The strength
demands are proposed to be in line with the standard EN 283.
4. To establish guidelines <strong>for</strong> stowage and securing <strong>of</strong> palletised cargo in railway wagons.
5. To require improved strength <strong>of</strong> the shunting hooks <strong>for</strong> new railway wagons improving
the possibility <strong>for</strong> safe transports in ferry traffic. Restrictions <strong>for</strong> which significant wave
height train ferries may operate in should be introduced.
6. To investigate reasons <strong>for</strong> cargo damages during railway transportation and to develop
means to avoid such.
