The lead locomotive is an General Electric ES44C4, which rides on three axle trucks, but only the leading and trailing axles are powered, making it an A1A-A1A wheel arrangement.
Couldn't make out the unit number on the trailing locomotive, but it has a different radiator, so it is probably a different variation of the ES44.
Why would they only have 2 axles driven??

Lower weight/loading per axle and enough electric motor power from two axle motors per truck. Has been common on diesel passenger locos since way back, often to increase route availability on older lines.

Not exactly a photo of Railroad tracks, but I picked up a section of rail and some spikes and hardware and made an Anvil.

I'm not sure how far back the arrangement was used, but the EMD E series of locomotives also used A1A-A1A wheel arrangements, as the were basically the power trains of two F series units on one longer chassis. Advancements in the power ratings of traction motors using AC technology has allowed a 4,400HP prime mover power four traction motors.
