1. Perspective IPT for Czech Republic and Network Capacity
2007 – 2009: R & D project CG723-138-190 – Configuration of IPT nodes in Czech Railway Network (Baudyš, K., Drábek, M., Janoš, V.
Kříž, M., Pospíšil, J.)
Results

Optimized configuration of IPT-nodes for long-distance transport
Long-distance and regional lines layout and timetable (netgraphs)
⇒ requirements for infrastructure improvements
Basic interval: 1 hour
On some long-distance lines interval densified to 30 min
On some suburban lines interval densified up to 15 min

2. Network-bound Periodic Freight Train Paths
On the present, only Trasse Schweiz AG offers periodic freight train
paths (to authors’ knowledge), which are only little bound together
in nodes
Freight railway, to be competitive, needs regular capacity during day,
despite dense passenger services
Generally, freight transport is not suitable for lines (miscellaneous
transport sources and destinations)
⇒ Both regularity (interval) and flexibility (directions) needed

Network Supply of Periodic Freight Train Paths
6
Specialities of freight timetabling

Steeper gradients ⇒ asymmetric running times X zero symmetry
(necessary for train path bindings in nodes)
Variety of running performance among freight trains ⇒ problem
with choice of „model train“ for periodic freight train paths
7
Interaction with Passenger IPT
For quantitatively and qualitatively sufficient capacity for freight trains,
there may be necessary to adjust some passenger train paths.
Train paths of express or (sub)urban trains are mostly hard to move,
because of too strict timetable bindings
⇒ Train paths of fast and regional trains remain to be adjusted
In some special cases, in conjunction with regional public transport
organizers, some municipalities adjacent to regional train stops can be
served by bus and the remaining ones by local fast train.

Designed Passenger Timetable

30-min-interval of fast trains (stops: Pardubice, Přelouč, Kolín)
30-min-interval of suburban trains (stops: almost everywhere)
Netgraph of passenger train lines between Pardubice and Kolín
(black – fast trains, dark blue – suburban trains)

Designed Train Diagram (One Direction)

Proposed Solution (in 1-hour time window)
1. Cancel (temporarily) regional line
2. Shift fast train paths closer to nearest express train paths, if possible
(check following sections till Prague Main Station)
3. Construct freight train paths with at most 1 stop (quality requirement)
4. Give back passenger train path (1 hourly is enough for the population
around regional train stops)

New Train Diagram (One Direction)

Results: Train Stop Policy

Hourly bus service instead; better accessibility in return (more stops)

Alternative Solutions for Regional Transport

Passage of regional train through Přelouč and stop in Řečany
Cancellation of regional line, aditional stop of fast trains in Řečany
or Chvaletice
Cancellation of some fast train lines
etc.

4. Conclusion

This paper should in no case serve for thoughtless freight lobbying
The problem of deterioration of current public transport supply is
delicate – even in case of few hundreds of inhabitants
In case of mere reduction of planned service extension, this dilemma
could be avoided
⇒ Multipartite dialogue is necessary.
