I guess that the most interesting part was how little total ghg benefit difference per trip comes from electric rail operations versus diesel electric, in total per trip emissions savings.
I was kind of shocked that with so much of the ghg savings coming from removing auto and air trips, that there was so little difference in savings there was between diesel-electric and electrified rail.
It makes a strong case, that if we had the choice of using money to put on more frequent and heavily used rail services, reducing way more auto trips, versus spending the same amount on RR electrification, with no new services, that putting more money into the services would product a much bigger ghg emissions saving.
Whatever you do FUD, don't tell CARB or the General Contractors Association lobbyist's pushing CARB to mandate only electrification to reduce GHG's.
You might really bum them out with dangerous seditious data like this.
