OVERCOMING THE CHALLENGES OF

OPERATING HEAVY AXLE-LOAD IN

NORTHERN SCANDINAVIA

Thomas Nordmark Rail Road Specialist

LKAB Business & Technology Development Sweden


INTRODUCTION

• Northern Scandinavia together with northern Russia is

called the Barents region and is very rich on natural

resources, oil & gas, minerals, lumber, hydro power, fish

INTRODUCTION


• 30 tonnes axle load now

upgrading to 32,5 tonnes.

INTRODUCTION

• The Ore line “Malmbanan”

between Luleå in south and

Narvik in north is the only

heavy haul railway i Europe

Kiruna - Narvik

Luleå - Malmberget 550m


FACTS MALMBANAN Built 1902 (single track), Annual gross load 40 MGT

Maximum speed 120 km/h, Maximum train length 750 m

Most curves 300 – 600 m, 12 ton/m, total length 540 km

ERTMS 2018, study for double track performed


FACTS ORE TRAIN

• 17 IORE locos, 15.000 hp, tractive effort 1200 kN

• 1150 Ore waggons, bottom discharge

• Speed 60 and 70 km/h

• Front end power and 68 cars = 750 m

• Total weight 8.500 ton

• Transport 30 Mton/annually


DEREGULATED RAIL WAY

• Application for train slots (8 months in advance)

• Access charges based on tonkm and train type

• Quality charges – penalty for delayed trains

ONE OF THE MOST SCENIC RAIL WAYS

IN THE WORLD – ANY CHALLENGES

FOR RUNNING HEAVY HAUL?


CONDITIONS - WINTER

Temperatures below - 40°C and snow depth 1 – 2 m.

Example

• Switch heaters is used

from October through

April.

• Gauge face lubrication

and ToR do not work

during winter.


CONDITIONS - WINTER


INTRODUCTION


CONDITIONS - SUMMER

• Summer: Extremely short period for track maintenance

Examples

• During 12 weeks (June – August) track work can be

performed. Take away 6 – 8 hours from traffic.

IORE THE ENERGY EFFICIENT LOCO

On the Riksgränsen-Narvik

stretch, energy expenses are zero

on the Norwegian side and the

energy gained there is sufficient to

power the empty trains back to

Riksgränsen.

A fully loaded

train set, running

the Malmberget-

Luleå stretch

without stopping,

can reach near-

zero energy

consumption.

Dual energy meters

measure consumed

and regenerated

electricity.

The use of regenerative

electric brakes on the

IORE locomotives has

meant annual energy

savings of about USD 2

million.

The CATO (Computer Aided

Train Operation) system

provides a 20 percent

reduction in energy costs.

CATO Among Leading Green Innovations world wide

To enhance performance of the Heavy Haul operation LKAB

and Trafikverket implemented 2011 an advanced On Line

Communication Based Driver Advisory System called CATO.

The idea was to:

- Save energy

- Less stops for loaded trains

- A more robust train schedule

- Better information to the driver

- Better communication between dispatcher and driver

SAFETY


Main objectives:

• More efficient train dispatching

and increased utilization of line

capacity

• Reduced energy and power

consumption

• Reduced wear on vehicles and

track

Supplier of system:

- optimal curve speeds

- adhesion, avoidance of excessive traction & breaking

- ”soft” speed restrictions for track defects

• The electro dynamic breaking together with new wagons with lower rolling resistance give an energy saving of 25 percent.

• The CATO system provide LKAB with a further saving of about USD 2 million per year.

• Electricity expenses for train operation at LKAB amount to about USD 9 million per year.

• Overall, the transition to new trains with modern technology, and continued investment in new technology, has reduced energy expenses for iron ore shipments by USD 5 million per year.

eMAINTENANCE

• On-line information is soon available from every train

passage – many GByte/train!

• How to incorporate this data into the maintenance

process?

• Need tools and routines to refine the data, present it, set

maintenance limits so we can take the right decisions in

our maintenance regime.

• A joint project is launched between Trafikverket, the

operators and the University of Luleå to demonstrate the

benefits. It´s called ePilot119.
