Just how much modification do trains need to run biodiesel? I asked the question over on the US Biodiesel and SVO forum yesterday in the light of the new Virgin 20% Biodiesel powered train.....
Suzy suggests:
I'd hazard a guess that it's just cleaning the fuel tanks to remove the crud and replacing the fuel lines and seals with biodiesel tolerant ones.
There's got to be more to it than that surely?
The only fuel spec I've been able to find on the web relates to a US standard for diesel loco fiuel. I can't find one for UK railway engines.
A bit more rooting about reveals that the British Rail Class 220/221 trains (to give them the name beloved by Anoracks the UK over) are fitted with four Cummins QSK19 diesel engines. I've put a call into Cummins...

"There's got to be more to it than that surely?"
Not at low (
Above 40% I can see SOME modifications may be required, particuarly if no additives have been added to the B100 prior to blending.
Other than that - if the blending has been done correctly, the B100 was fresh, and made to EN 14214 - then the fuel "may" actually be better for the engine than standard diesel!!
Great news.
