Deploying I-ETMS:

“What do I need to know???”

• “Why should I care?” • I-ETMS Overview • “How hard can it be?”

Agenda

“Why should I care?”

Do you have to deploy PTC?

• Are you a Class 1 railroad?

– Required to deploy PTC on track and locomotives

• Do you host passenger traffic?

– Required to deploy PTC on track and locomotives

• Are you a tenant on track that is PTC required or operate

over a diamond where PTC is required (236.1005(a)(1)(i))?

– Deploy PTC on locomotive(s)

– Possible Office integration, servers, training, & configuration

management

– PTCSP submittals

Locomotive I-ETMS Installation

NS is installing:

• TMCs- Runs I-ETMS software

• CDUs- Crew interface to I-ETMS

• Cut-Out switches- Provides for failure bypass

• Sensor cabling- Provides loco data to TMC

• ITCMS- Provides interoperable message

routing

• Onboard Network- Provides IP Cell/Wifi

devices and CDUs

• 220 MHz Radio- Provides office/wayside

interoperable communications

• Antennas- 2xGPS, Cell, WiFi, 220MHz

16

Requires:

• Trained work-force (employee or contractor)

• Installation procedures for various loco types

• FRA witnessed installation

• PTC commissioning

• Maintenance standards

• Configuration Management

Locomotive I-ETMS Installation

Locomotive: Multiple Models & Configurations

Norfolk Southern has more than 250 different configurations of locomotives. Same model locomotives vary by year, previous owner(s), modifications made during the life of the locomotive, and by FRA standards at the time of manufacture or previous modification

Locomotive: CDU Display Installation

NS Objectives for CDU Installation • Must be readable from seat position • Must be able to reach buttons from

seat position • Must not block view out windows • Must not block other required

information • Must be maintainable • Must not cause an unsafe condition,

knee knocker • NS & BLE cab committee

19

Locomotive: CDU Display Installation

Some are easy

Some are more difficult

20

Locomotive: Space Constraints

Some units accommodate additional PTC technology onboard

21

Locomotive: Space Constraints

Some do not

22

Locomotive: Antenna Arrays

Each locomotive has its own array of antenna that must be installed. This array must also be retouched to add yet more antennae.

Configuration Management Overview

• Common Safety Plan: Configuration Management

Overview

• Development/Deployment/Track Data Change

• I-ETMS System Configuration Items

• Industry Coordination

24

Safety Plan: Configuration

Management

§ 236.1015 PTC Safety Plan content requirements …

Section (d)(9) A complete description of the configuration or revision

control measures designed to ensure that the railroad or its contractor

does not adversely affect the safety-functional requirements and that

safety-critical hazard mitigation processes are not compromised as a

result of any such change;

Development Change

Deployment Change

Track Data Change

Each railroad develops their own CM plan, which integrates with these processes

25

Change Management Processes

Development Change

Deployment Change

Track Data Change

Supports management of proposed I-ETMS system

changes, both Interoperable & Non-Interoperable, which

impact the functional or non-functional behavior of the

system.

Supports safe and reliable implementation of approved

Interoperable Development Changes into an operational

train control environment.

Supports safe and reliable implementation of changes

to Track Data, utilizing the railroads Track Data

Verification and Validation processes.
