  1. Energy saved by rail-road results of the shipper and operator survey Christophe Rizet Nicolas Lebelle Jacques Léonardi

  2. Part one : Method and dataThe 2 types of rail road : maritime containers operated by Naviland Cargo swap bodies operated by Novatrans

  3. 2 networks per type of rail road : Novatrans (swap bodies ) & Naviland Cargo (TEUs)

  4. Objectives • The development of Rail-Road transport is often presented as one of the solutions to reduce energy consumption of freight transport • The French S.O.Survey includes a sample of RR shipments • The tracking of these shipments along the chain, enables to compute • Energy consumed by this shipment on the rail-road • Energy that this shipment would have consumed by road

  5. The RR chain versus road only

  6. The sample of RR shipments • Sample is part of INRETS 2004 SOSurvey • 108 RR shipments observed ; 93 used here • 15 maritimes containers 78 swap bodies • 18 international ; 75 domestic (French) • Used without statistical weights

  7. Main assumptions • Road legs of RR chains : 2 Hypothesis H1 minimum ‘empty’ back hauling = 100 % of loaded leg (with the empty box) H2 ‘empty’ back hauling = 300% of loaded leg (bringing the empty box to the shipper, empty back, going back empty to the shipper and bringing the box the the RR terminal) • Road only case : Empty back hauling = national average : 28 % of the loaded leg • 1liter Gazole = 0.85 Kgoe • 1MWh = 86 Kgoe (equivalence at the consumption)

  8. Energy efficiency Rail & Road (Road : semi trailer 12,5 t. payload, 35 l/100 km) Rail energy consumption /tkm = 1/5th of road

  9. Part Two : Results Distances • Rail versus road (rail leg) • Rail-road versus road only (H1 & H2) Energy kgoe/shipment • Rail-Road H1 versus Rail-Road H2 • Rail-Road H1 versus Road • Rail-Road H2 versus Road

  10. Rail legs of rail-road chains in our sample are on average, slightly longer (12%) than the road distance

  11. H1 : The distance of the RR transport chain is on average (32%) longer than the road only transport

  12. H2 : The distance of the RR transport chain is on average (56%) longer than the road only transport

  13. In the H1 assumption, rail-road transport chains consume half (53%) of road only

  14. In the H2 assumption, rail-road transport chains consume 2/3 (66%) of road only

  15. ConclusionFrench Rail-Road is energy efficient under the assumption :1MWh = 86 kgoeThe Shipper survey is a powerfull toolThank you for attention
