MTA METRO AT A GLANCE
♦ Grade separated♦ 11th Largest in the US – Nearly 15 Million Passenger
Trips Annually♦ 15.5 miles long
• Owings Mills to Johns Hopkins Hospital♦ Dedicated inbound and outbound track♦ Single Maintenance and Storage Yard♦ 14 mainline stations (6 above ground/ 8 underground)♦ Powered by 750 VDC Third Rail♦ Current Fleet of 100 Vehicles and Train Control
System are 35 years old• Original Railcars – Budd Company• Original Train Control – Ansaldo Breda
♦ Headway• 8 Minutes Peak• 10 to 15 Minutes Off-peak
METRO HISTORY
4
• Phase 1 Section A (Northwest Line): was completed in November 1983 and it extends northwest from downtown Baltimore. It consists of a 5.55-mile underground section and a 2-mile aerial section.
• Phase 2 Section B (Northwest Line extension): was completed in July of 1987 and operates at grade level. It extends for 6 miles.
• Phase 3 Section C (Northeast Line): was completed in 1996. It is 1.5 miles long and it operates Northeast underground from the city center.
Train Control Project Overview♦ Data Communications System (DCS):
• Fiber Optic Cable System (FOCS)• Ground Based Network (GBN)• Wireless Communication System (WCS)
♦ Solid State Interlockings with existing signals, switches, and snow melters
♦ CBTC – Zone Controllers and Carborne Controllers
♦ ATS: Hardware/software and interfaces to SCADA, “Next Train Arrival” messaging, and Google Transit
♦ Axle counters♦ Yard Test Track♦ Removal of existing track circuits
Phased Installation for Brownfield Success
P2SSI Installation – Continue
revenue operation with existing fleet
P3 Install and commission backup/primary ATS
P1 Install and Commission new DCS P4
Install and commission CBTC wayside and room equipment in
segments
P5Delivery and dynamic testing of
new railcars. New cars increase, old cars decrease
P6Install new wayside cables and
remove AF track circuits in sections
All work will begin at OM and move towards JH
Migration/Cutover Planning
♦ Phase 1 – DCS (Fiber, GBN, WCS)• All fiber and network hardware installed. • Wireless access points installed• No cutovers during Phase 1• Utilize existing conduit as much as possible
o Remove unused cables – highway encroachment, sound phoneo Move wayside cable replacement from Phase 2 to Phase 6 – allowing conduits
to be freed later in the project.
Migration/Cutover Planning – Phase 1 DCS
Migration/Cutover Planning – Phase 1 DCS
♦ In order to progress work to Phase 2 before Phase 1 is complete, a portion of the North Ring will be closed as the first SSI locations go into service.
Migration/Cutover Planning
♦ Phase 2 – SSI Installation OM to JH• Microlok installation begins at OM working towards JH. • Testing will be conducted during non-revenue service from Midnight to
4AM. • Over and Back (Existing to New) is accomplished by removing and
replacing plug couplers into defined mating connections• Existing fleet is in operation with Microlok control of all existing track circuit
equipment. • Requires interface to existing train management system and existing track
circuits. Existing ATS provides control and monitoring during Phase 2.• Locations will be released for revenue service once installed, tested, and
safety certified.

Migration/Cutover Planning
♦ Phase 3 – Primary/Backup ATS• MTA has a Primary OCC and a Backup OCC, which also serves as a training
location. • Migration to the new ATS will take advantage of the existence of a BOCC by
installing, testing, and commissioning in that location first. Allowing system to be fully implemented and tested.
• BOCC will control and monitor the line while the new ATS equipment is installed and commissioned in the MOCC.
• Once the MOCC is tested and commissioned, the system will be entirely controlled and monitored by the new ATS.
• Requires interface to existing SCADA System. o Existing ATS will continue to serve to gather field I/O for MTA’s SCADA system. An
intermediate server with serve as data pass-through to the new ATS. This provides a clear demarcation of responsibility for the two system. SCADA will remain in service after the project is complete.

Migration/Cutover Planning
♦ Phase 4 – CBTC Goes Into Service• Install and commission wayside and on-board CBTC for the Pilot Train (3
Married Pair Train)• Low speed testing can occur on the test track at Wabash Yard. Full-speed
testing will occur on the main-line• Mixed mode operation begins. Non-CBTC Trains will operate with fixed
block. CBTC Trains will utilize MAL• Phase 4 culminates in revenue service of the

♦ Phase 6 – Install new wayside cables and Remove AF track circuits in sections.
• All new vehicles will be in service under CBTC Control. • Axle counters will be installed.• Wayside cables will be installed as track circuit cables are
removed and conduits are made available.
