Introduction to rail transport
The core area of rail freight transport includes the commercial transport services
with freight trains !part from the actual transport of goods" preparations" follow-
up procedures and processes are also part in the commercial transport services
#ue to the s$stem properties infrastructure companies are heavil$ involved in the
production process and support the production %ualit$
The transport s$stem needs the rail transport mode services in places where
cargoes are transported long distances &n 'entral urope" the rail freight has
strong position ecause of the growth in container and ul* transport and theincreasing importance of intermodal freight transport &n urope (e+cluding '&,
countries) the volume of transport was altogether 32 illion tonne-*ilometers in
2010 (./ vs 200)
owever" the largest contriution with 32 illion tonne-*ilometers was
achieved in !sia and 4ceania &n worldwide the total volume of transport was
281 illion tonne-*ilometers in 2010
The main disadvantage of rail freight is its lac* of e+iilit$ 6or this reason" rail
has lost much of the freight usiness to road transport 7an$ governments are
now tr$ing to encourage more freight onto trains" ecause of the environmentalenets that it would ring9 rail transport is ver$ energ$ e:cient
&ntermodal transport is a sut$pe of multimodal transport and descries a multi-
unit transport chain" where one and the same transport or loading unit is
transported $ at least two di;erent modes of transport
The term intermodalit$ was rst used in the

ac*ground and the transport chain etween several modes or techni%ues was
promoted This produced various cominations of connections etween maritime
and inland waterwa$s" road vehicles" railwa$s" pipelines and even airplanes

T#pical $actors $or the rail transport
T$pical factors for the rail transport are@
- 6orward and ac*ward forces can e large due to when wagons are
shunted or during ra*ing ,hunting means the operation where wagons
are moved to another trac*
- ,ide forces can e also large due to oscillation which is a *ind of $aw orswing 4scillation is composed of short transverse movements of wagons
during transport 4scillation or swinging characteristic can e oserved in
passenger wagon when $ou are travelling $ train
- Aong Bourne$ can create long lasting forces
- The train is t$pical choice of the modes when $ou need to transport heav$
cargo
- The road transport compan$ has to ta*e into account the rail transport
re%uirements" ecause there e+ist di;erences in cargo securingre%uirements etween these modes
- The rail transport compan$ has three transport service t$pes@
conventional" intermodal and multimodal" in which ever$ t$pe have its own
guidelines for cargo securing 'onventional service means that goods are
loaded at the shipper and transported to the customer for unload

! at rac* with end walls uses less volume when transported empt$ and

The internal height of a platform-ased container with 7M> according to the &,4-
standard is often less than the height mentioned in the standard for a freight
container >ith the internal height means the distance etween the oor and the
upper edge of the upper corner ttings Nou should not use the total internal
height since a container or at rac* stac*ed on top of the platform-ased
container can sag and destro$ the cargo
The height of the platform oor has to e appro+ 00 mm to carr$ the loads from
the cargo" which means that the internal height is signicantl$ lower than for a
general container &n some cases the internal length can also e consideral$
shorter than for a general container as the end walls have to e made strong to
withstand the designing forces
