Size of the Pie Parked train is a

Stabled train or

Waiting longer than 15 minutes at a station or

Sat in sidings idling

Trainer Project identified

10% of Energy consumed is by parked trains

50% of this could be saved

Process

Figure 1. Process Management Principles for Energy Efficiency: applied toparked trains. (Derived from Process Power People)

Some targets and objectives should be set for management of

parked trains

Some targets and objectives should be set for management of

parked trains

Roles and responsibilities should be definedRoles and responsibilities should be defined

Management should ensure staff are educated on the potential

benefits sought and why and that they are trained in the

techniques to deliver these savings

KPIs should be set for the energy consumption of parked trains

and the sub systems that contribute to this consumption and

these should be monitored by management

Practical Measures


7/23

Better Insulation Most vehicles contain this Some more than others Some train operators citing different U

factors kW/m2K Can be implemented during overhaul Ensure good seals on windows and doors

Est. saving 20% of HVAC energyconsumption (parked or not)

Recommendation: UIC leaflet to specify Uvalue for trains

http://www.insulation-guide.com/save-with-insulation.html


8/23

LED Lighting 3-13Watts LED vs 75-100Watts Bulb

Last up to ten times longer

Can be dimmed

Reduce heating load for HVAC to deal with

Not cost efficient as a one off fleet fitment but

can be done fit on fail

9/23

Window Films 3M claim 35% of heat can be reflected

UV protection up to 99%

Could be supplied with anti scratch properties

Pendolinos fitted in the UK


can be supplied pre fitted to the Glass pain fit on fail

10/23

Triple Glazing According to Thermotech insulates ~60% better


Can fit on failhttp://www.thermotechfiberglass.com/WhyTripleGlazed.htm


11/23

Varying HVAC Settings annually Higher interior temperature in Summer

Lower interior temperature in Winter

No figures but logical saving and easy to do

Theory is people wear more clothes in Winter

and less in summer

NoChance!


12/23

Passive


13/23

Closing Doors and Windows Windows and

Doors


14/23

Manually Isolating HVAC

Savings based on type of HVAC equipment andduration of standby


15/23

Engine shutdown Test Cycle F reveals engines

spend ~60% of their timeidling

Possible to reduce byswitching off engines onparked trains

Savings based on engine typeand no of engines shut down


16/23

Active


17/23

Door Auto CloseRecommendation: UIC

leaflet to specify U valuefor trains


18/23

Ancillary systems shutdown Can ancillary systems be shut down?

Recommendation: UIC leaflet to specify U value fortrains


19/23

Auto stabling mode Able to remotely switch on HVAC, Lighting, etc

Could be automated based on timetable

Reliability/Availability benefits from knowing

condition of train


20/23


21/23

Conclusions Energy Savings are possible

At low cost and

With additional benefits

Some can be done now but

Some are better done during overhaul or

New train Procurement


22/23

Recommendations Operators to develop a high level policy using steps

outlined in Process, Power, People

Techniques shown today should be considered usingthis framework

UIC to develop Insulation standards

Clear instructions to staff on what equipment tomanually isolate, When and How

CEN to standardise Auto close

Rail Sector to consider an EN specifying Auto Stablefunctionality into new trains
