running at Riverside i rarely get to see locomotives other than in basic black, so i enjoy traveling out to Maricopa to see some pretty diesel units run...
not sure if these are the same SantaFe locomotives...
but there typically isn't a shortage of F units to watch.
to not break the bank, you can get started on something smaller than an A-B-B-A hookup like this TrainWorks (i think) SW1500 though the slug is a nice touch doubling as an operator riding car.
fun stuff...gary
