• The function of EX-TREMIS stays very close to the Railion vaules in a range from
600 to 1800 gross tonnes.
• Some values from UIC statistics are higher than the Railion values, but the majority
are in line with it.

A new function is generated for EcoTransIT World which includes the following assumptions:
• Train weight between 600 and 1800 gross tonnes the Railion values correlate well
with the function of EX-TREMIS and most of the UIC-values. Therefore the following
function correlated to these values is figured:
EC spec [Wh/Gtkm] = 1200 * GTW -0,62
(
ECspec: specific Energy Consumption, GTW: Gross Tonne Weight)
• Below 600 gross tonnes the diffusion of the values is higher. This means a higher
uncertainty of the values. We propose to use the same function as for the middle
weight trains due to define the function as simple as possible.
• Above 1500 gross tonnes the Railion values show no significant reduction of specific
energy consumption with growing train weight. This general trend is confirmed by
values of heavy trains (4000 gross tonnes and more) for Canada, China, and USA.
Therefore we propose to use the function until 2200 gross tonnes (specific energy
value: 10 Wh/Gtkm) and then keep it constant for larger trains.
