Excellent video Colin!

[@aezoss11]

Great shot of the BNSF + KCS @ 1:05:00 with the mountains in the background and eagle soaring overhead. Hope you got a high res still of that!

[@johnniebellamy5912]

That Green Locomotive Was Very Interesting Looking

[@PasadenaSubColin]

It's pretty neat. It's a genset and has two small prime movers as opposed to one large one

[@markjohnson4924]

@@PasadenaSubColin Why wasn't it belching out tons of smoke?

[@PasadenaSubColin]

low emissions, makes less pollution than an older diesel since it was built during T2 regulations
