Title: Counting output in ways that matter: lessons from Britain


1
Counting output in ways that matter lessons
from Britains Railwaysor
  • Dr Tim Leunig Professor Nick Crafts

2
Why have commuters been neglected since 1945?
  • Dr Tim Leunig Professor Nick Crafts

Measuring output

  • Passenger miles

Measuring output
  • Passenger journeys
  • Passenger miles
  • Rather crude, and not quality adjusted

Counting output correctly
6
Aspects of quality
  • Are the trains safe?
  • Are the trains fast?
  • Are the trains frequent?
  • Are the trains on time?
  • Can I get a seat?
  • Are the sandwiches any good?

7
Fast v frequent
  • People want to get from origin to destination,
    quickly
  • Quickly means the time from when they want to
    leave until actual arrival
  • Train speed and frequency are therefore
    substitutes and need to be considered together

Methodology (1)
  • Computerise the railway timetable
  • Find out how speeds and frequency change over
    time
  • Take into account that trains at some times of
    day are more important than at others

Which train to catch?
  • Preferred time of travel exogenous
  • Take the first train after the time you want to
    travel
  • Except do not take a train that will be overtaken
    by a later train mid-journey
  • No endogeneity of preferred time of travel as a
    result of train speeds

Which journeys to include?
  • Representative selection?
  • Major journeys?

Which journeys to include
  • Representative selection?
  • Major journeys?
  • Journeys of different types

5 samples
  • Short commuter routes (Surbiton)
  • Long commuter routes (Cambridge)
  • Long distance routes (Leeds)
  • Non-London routes
  • Airport connections

Overall result
  • Since 1945, long distance trains have become
    faster
  • Shorter distance commuter trains got faster until
    the earlier 1970s, and have since slowed down to
    their 1950 levels again

Commuter line quantity
  • 375 million commuter journeys into Central London
    each year, 60m from Waterloo alone

The value of time
  • DoT methodology modal-specific wage values for
    in work time, standardised for other time
  • Rail work time 42/hour
  • Commuting time all modes 5.75
  • Commuting rail time would be 8
  • Might be higher into SW London?

22
Lost value
  • Counterfactual commuter trains get faster at the
    same rate as non-commuter trains since 1950
  • eg Surbiton-Waterloo 14 mins inc waiting (51mph
    total, 71mph IV on current frequency)
  • Value _at_8/hr 440m (npv 6bn)

23
So why hasnt it happened?
  • Politics?
  • Technical difficulties?

24
Commuter line politics
  • In commuter constituencies, lots of people
    commute salience
  • Non-commuting home owners gain as house prices
    reflect service
  • Therefore you might expect government to improve
    these lines

25
Commuter line politics
  • Most London commuter constituencies vote
    Conservative
  • And some are politically marginal Croydon,
    North Kent, South Essex

Can commuter routes get faster?
  • Improve signalling to run more trains per hour
    (as in 1912)
  • Lighter trains accelerate more quickly
  • More doors to speed boarding
  • Tunnel mainline routes into the centre, (e.g.
    Waterloo Bank Liverpool St) big time
    savings

Why choose HST instead?
  • Glamour? Announcing that Britain will enter the
    High Speed Era with the CTRL or the WCML may get
    better headlines than announcing 5 minutes off
    the time to East Croydon.

Evening Standard
  • The Queen re-ignited the great British love
    affair with the railways last night as she opened
    the revitalised St.Pancras station.
  • History was made at the new St.Pancras
    International today when the first Eurostar train
    left for Brussels.

Will it happen?
  • Eddington talked about building what people will
    use
  • Crossrail is in London (although does not seem
    designed to maximise outputcost ratio)

train to work so slow?
