Challenges for Heavy Haul Railroads
Increase production, reduce costs, innovations, automation, optimization

Challenges for Heavy Haul Railroads
Increase production
• Use existing capacity most efficiently
• Identify capacity bottlenecks
• Increase network capacity most efficiently
Reduce operational costs
• Reduce asset idleness
• Improve manpower utilization
• Use optimization technology
13 © Optym
Complexities Created by New Technologies
New upcoming technologies are making rail operations more
complex and right software is required to take advantage:
• Driverless Trains
• Communications-Based Train Control
• Virtual Block & Moving Block
• Auto Route Settings (ARS)
Full benefits of these technologies can be obtained only when
the entire rail system is optimized end-to-end.
Optimization will be critical to create ROI to pay for these
technologies.

Increasing Optimization
Less reliance on human experience.
Do more with less people.
Capture human intelligence of your
operations into software solutions.
Build a GPS like solution that will
guide the entire rail operation.
15 © Optym
Potential Benefits on Optimization
We can increase network capacity
by at least 10%.
We can reduce operational cost by
at least 10%.

Optimization to Become All Pervasive
Creating better plans Executing plans better Analyzing results and identifying areas
for improvement
Planning Execution Visibility & Analysis
Role of optimization

Important Planning Decisions
When and where to have maintenances to have
minimum impact on train operations.
How many trains to run and at what times to meet
product demands.
Create detailed schedules of all trains while
creating enough opportunities for maintenances.
Create plans that are realistic, can be followed
and disseminate them among all stakeholders.
These plans will form the basis for execution.

Rail Planning Tool: Overview
Rail Planning Tool will determine how many trains to run, when to run, which
products to load from, which car dumper to go, and how to do meet-pass conflict
resolution.
Schedule of Trains (Train Departure Times,
Product Loadouts & Car Dumper
Assignment)
Arrival Schedule of Trains at all Locations
including Loadouts and Car Dumpers
Analytics & Reporting

RPT
Outputs
Ship Schedule
Product Demand
Loadout Availability
Track/Switch Availability
Car Dumper Availability
Rolling Stock Capacity
Maintenance Schedules

Greater Capability for Rail Planners
Rail Planners will plan operations for one
day to several weeks ahead in future.
Rail Planners will determine the feasibility of
meeting customer demands by taking into
account various network and resource
capacities.
Rail Planners will also use this tool to plan
for track, switch and signal maintenances.

Rail Planning Tool Features
Multiple users with
privilege
management
Ability to create
multiple what-if
scenarios
Ability to analyze,
compare and
publish scenarios
Use latest optimization
technology, evaluate
various options and
recommend best
option
23 © Optym
Important Execution Decisions
Execute the plan created by the planning system.
Receive data from various sources in real-time and adjust plans
to account for disruptions.
• Rolling stock availability
• Crew availability
• Track availability
• Car dumper and loadout availability
• Product need
Execution system will run in real-time and produce decisions for
train controllers to follow.

25 © Optym
Train Control System’s Capability
Building of Intelligent ETG (Electronic Train
Graph).
ETG will have drag and drop and touch screen
capabilities.
Same system used by all train controllers and
rail planners with full visibility to everyone.
Train controllers will be able to perform all of
their day-to-day functions using ETG efficiently
in less time and with less people.
26 © Optym
Expanding Train Control System’s Role
Intelligent train control systems will
resolve all meet-pass train conflicts.
Meet-pass planning will be goal-driven
and user configurable.
Humans will only do exceptions
management.
All decisions related to train routings
will be communicated to ARS and
switches will be automatically lined up.
27 © Optym
Real-Time Visibility & Analytics
Have full visibility of all rail operations in real-time and proactively manage them.
28 © Optym
Moving from Static Reporting to Dynamic Analytics
Faster User Focused Mobile Simpler Relevant
29 © Optym
Visibility and Analysis
Real-time dashboards
monitoring system behavior
and KPIs.
Historical analysis of past
data and playback
capabilities.
Proactive analytics with focus
on actionable decisions.
