I've had a go at it myself but it's bit too hard for me. I need three locos and two passenger cars, I would like Sierra Northern railway numbers 131 and 133. And I would like 136 in Sacramento River Train livery. And 2 or more cars at least one Sacramento River Train open air car (691) and a lightweight car (the car American) in the Sacramento River Train gold and dark blue livery (the most recent livery)
