Energy cost and CO2 rejection of a train

[Christophe]

The consumption of my car does not vary if I refuel with 95% of the empty tank or 50% ....

Ben on my vfr and the twingo I assure you that I see a difference ... after 700 km on the twingo we consume less than refueling 500 ... promised spit ... but it's can be an illusion because of the increased accuracy?

[Christophe]

Do you explain to me how you do 1200 km per day at 30 per hour?
