WileeCoyoteI guess you guys are looking to haul a couple miles of freight, huh?
This is quite a valid question I find, given that I also do a lot of freight operations. Most of the time I couple several American locos together (especially Dash-9's, I love em'), but in the case where I absolutely need to have one loco, I use one of these monsters.
A former (now owned by CoonRail Logistics) RZD 3TE10M clags over a lake with a rake of container wagons.
How much power it has I don't know exactly, what I do know is that it is incredibly powerful and can be used for pretty much any heavy logistical need.
