• The Kansas City Southern Railway (KCSR) had a need to modernize an outdated microwave system in preparation for a PTC deployment

• Microwave system is made up of 48 sites than runs through 5 states

• Primarily paths run North/South from Kansas City to Beaumont and New Orleans

• Multi year project• Phase I included sites South of Shreveport• Phase II included sites North of Shreveport

Legacy to IP Microwave Conversion

• New system needed to be capable of handling PTC data transfer requirements

• New microwave radios needed to be implemented with failover capability in mind

• Tower infrastructure needed upgrading where for enhanced reliability

• Needed to be deployed with a minimal impact to the business

• There was legacy equipment that needed to remain post cutover not capable of communicating over IP

• Had to find an interface solution– Distributed Power (DP) repeaters– Wind speed indicators– Cameras– Base Communication Package (BCP) communication to backoffice.– Dispatch radios

DP Repeaters • Relays communication between locomotives in a train consist

• CPU for two zones located at master end, limited equipment located at remote end, each end equipped with one multichannel transmitter and four independent receivers at 450 Mhz

• OLD – Used E&M channels  via mux equipment.  Mod/Dem for data transmission, E&M for PTT and Channel Selection

• NEW – Duplicated configuration using E&M interfaces on routers.

Signal is received at Horatio on the corrsponding ch. according to the chart. The signal is sent to Rich Mt. Master DP repeater. Repeater then selects TX freq via ch. select bits 0 & 1. See chart. Then master keys tx via M lead on ch 4. Signal goes out on mod of ch. 4

and is transmitted on the correct frequency.

T1 Interfaces • It was determined during 1 for 1 evaluation that legacy wireless T‐1 circuits needed to be maintained after cutover, supporting backup for leased T‐1 circuits

• The solution was to emulate T‐1 circuits across the ethernetnetwork

• This was accomplished using Cisco routers with T‐1 interfaces

• Main issue to overcome was determining the correct clocking environment for the T‐1s over multiple router hops

• Phase I– General DataComm (“GDC”) multi‐plex units were being used for re‐

routing and T1 interfaces on the legacy microwave system– Chose to use Huawei AR 4549 routers recommended by GDC for the IP 

routing

• Phase II– KCSR converted to Cisco core network devices before this phase began– Implemented Cisco 3925 routers instead of the Huawei routers in the 

first phase– Utilize Cisco certified network engineers on staff

• A site package, containing all necessary equipment, hardware, and drawings was created and delivered to each location to assist technicians during the install and cutover

• All cabling, power connections, and grounding terminations were completed before equipment was put in service

• Racks were staged at field locations to minimize down time• Utilized diversity antennas during cutover

– One set of antennas used for the legacy radios, second set used for new radios

– Kept the legacy microwave in service until cutover complete

• Gained an understanding of Ethernet microwave radios– Reduced latency– Better bandwidth utilization– Scalable

• Realized that the data network had to be prepared so it could handle “communications” traffic 

• Gained an understanding of dynamic routing (OSPF).  Before this project we only used static routing in the network.

• Realized the importance of getting design help from data network engineers.  Didn’t have adequate network engineering support on the first phase.

• Not all legacy equipment that had to say on‐site was IP capable and not all vendors offer IP solutions

• Had to design interfaces between some legacy equipment and new IP radios

• Had to learn new diagnostic and trouble shooting techniques• Network Engineering and Communication Engineering teams 

have to work more closely together • New radios are IP devices on the network, have to become
