Designing a New Train Ian Walmsley Engineering Development Manager Porterbrook 1

ROSCO - Our business         Simple business model Long term assets Short term customers Straight Line depreciation Gosplan economics Market should be predictable Policy isn’t Pre-emptive work = high risk 2

What’s good for us?    Stock stays on lease for 35 years Minimum changes to achieve this Rolling stock should be: • Reliable • Comfortable • Energy efficient • Low maintenance • Coupling compatible • Suitable for the service • Adaptable for other services 3

An example        High reliability (90,000 mpc) Regenerative Braking (15% less energy) AC traction, low maintenance Compliant to modern safety standards Compliant to disability regulations Air conditioned, good ride, modern interior Perfectly designed for the service it operates  Risk of displacement? 4

Lesson learned  The best train doesn’t always win  Economy beats quality The Department is particularly interested to see rolling stock used on airport services that is better suited to the needs of airport passengers; Page 81 TSGN ITT Sept 2013 10

The UK rolling stock market is neither free nor controlled 11

Market and cost     12 Rail 2% of market Modal transfer CO2 Reduction Capacity of system

Market and cost Train is 15% of industry cost : 12% capital + 3% Maintenance 13

New train specification – Non-compliances                       GSM link to PIS Coupling with doors open GOP panel full function Current standards Ride better than 450 Inter-Vehicle damping Noise – new standard Reliability 340,000 MTIN Water tank gauge Insulation infra-red scan Dead haulage in service to 90 mph Light flash guard position 1450mm wide doors Standbacks at doors Footsteps cannot obstruct doors Emergency brake in Neutral No hill start button Sanding – dedicated power supply Low sand indicator Sandbox trace heating WSP failure alarm P12 Profile wheels                      14 Wheelset coating to minimise UAT Option for flange lubrication GSMR radio fitted Maintenance free batteries PIS letter descenders uncompressed Coach letter display in train Side of train PIS displays Wi-Fi remote upload PIS OTMR – GSMR Interface OTMR 7-day recording OTMR flash card download Train Manager’s office 275 seats (270) Emergency light power supplies No bonded glass Ergonomic layout for vehicle on it’s side Seat re-arrange with same body panels Toilet flush with lid up CCTV viewing screen Power close cab door ERTMS space provision and supply

New train requirement  Use existing design? • • • • •  Produce new design? • • • • • Capacity Acceleration 24 tph New technology Competition 15 Higher risk Design costs Safety Case Potential market Maintenance cost

Safety is a “given”         Rail Group Standards Codes of practice European standards Disabled legislation Fire regulations Accident reports Design review Acceptance bodies         16 Crashworthiness Materials used Control logic Redundancy Human Factors Stepping distances Electrical Interference Kinematic Envelope

Market divisions     High Speed Lines Inter-City Outer Suburban Commuter Inner Suburban Metro 17

New train decisions - speed  Maximum Speed • • • • • • 140 mph 125 mph 118 mph 100 mph 90 mph 75 mph        21 Track costs Train weight limits Installed power Braking ability Acceleration No. Powered axles Cost

New train decisions - length      3, 4 or 5 car 20m long 23m long 26m long 16.6m long        22 Platform Lengths Selective Door Opening Station dwell times No. of bogies Weight (Energy, track) Axle load (speed) Expected capacity need

New train decisions - doors       End or 1/3 – 2/3? How many? How wide? Standbacks? Swing/Slide Control       23 Doorway = 8 seats Standbacks = 8 seats Weight (Pass/m2) Speed of operation Reliability FASDO

New train decisions - Seats      How many? Legroom Rake angle Armrests Tables      24 Less seats, More people Crashworthiness Weight Cost Resistance to damage

Limiting case design 26

Limiting case design      Centre section peak operation sets design Bedford – Brighton 2 hrs 15 min Thameslink & Crossrail – same problem Not ideal for off-peak journeys Is there a choice? 27

The “Platform”     Need to spread design cost Make design flexible around a fixed “platform” New trains around country will be similar Platform designs usually last about 10 years 1970s 1960s 1990s 1980s 28 2000s

Maintenance Options - 1  All inclusive deal with manufacturer • • • • •     Capital Depots Materials Depot maintenance Major overhaul Only specify number of diagrams to be covered Best incentive to minimise maintenance cost Usually most expensive deal – risk brings reward “Wet” lease with ROSCO “Power by the hour” 29

Maintenance Options - 2  “Soggy” lease with ROSCO • • • • •     Capital rental Non-cap for overhaul Operator maintains Network Rail facilities Contract sets responsibility Operator controls daily availability “Lumpy” overhaul and repair costs smoothed out Terms to fit franchises System used when privatised in 1994 30

Maintenance Options - 3  “Dry” lease with ROSCO • • • • •     Capital rental only No “maintenance reserve” Operator maintains ROSCO audits asset Redelivery inspections Operator controls all aspects Lower initial cost Higher risk to operator – design and endemic faults Operators often expect support not paid for 31

Residual Value  Franchise operators come and go  ROSCO carries residual value  Example:- • • • • 200 vehicles at £1.7m each = £340M investment. Assumed a 35 year life After 7 year franchise residual value is 28/35 of £340M £272M  Risk may be backed off to Government  No more diesels 32

Conclusions  Designing a train is a series of compromises  Designs will primarily aim at one of 4 markets • • • • High Speed Inter City Suburban Metro  Adaptable for different routes – the “Platform”  Residual Value (i.e. life) very important 33
