My beloved 48 I love this little locos to death been a fa of them all my life and I’m 73 ,,lovely video t y ❤️🙏🕯️🇦🇺🦘🧌

I bet the crew was glad they didn't have 15 now ballast wagons extra on, with those old girls working their heart's out on a maximum tonnage up some stiff grades. Would this train weigh about 2,500 tons on 1 in 40ish grades, man they sounded better than listening to the modern locomotives plus their Australian made. Thank you for sharing this with us.

What happened to the 48s class? 7:06 smoke clouds!

[@Aaron-uf3sl]

Typically it’s turbo lag with the ALCo’s that causes the smoke. Driver takes a notch, engine does what it needs to do and delivers more fuel as required but the turbo isn’t supplying enough air at that stage for optimal air/fuel ratio for combustion.

It's a spotting characteristic of ALCo engines that. Makes an ALCo gunzel's heart skip a beat. They really smoke if they've been idling for awhile first. The engine is controlled by a governor from idle to notch 8. Each notch is a set RPM. Idle and notch 1 are usually the same RPM except notch one has electrical traction available to it which the governor adds fuel to maintain meaning sometimes the engine smokes without a change in RPM. As the driver sets the notch, the governor moves the fuel rack to maintain the set RPM of that notch. It acts quickly. Electrical load determines how much fuel is added because the notch RPM is the notch RPM and fuel is infinitely varied to maintain that notch's RPM depending on electrical load which is effected by train speed, weight and grade. The turbocharger has mass. The spool time cause by turbo mass and exhaust volume lags behind the governor fuel change, meaning delightful ozone depleting, climate warming, extinction causing visible smoke. Invisible 'smoke' causes these things too but out of sight out of mind right? EMDs are different since the blower (or turbocharger if fitted) are mechanically connected to the crankshaft. EMD turbochargers are crank driven at certain phases of operation and free spool in other phases and are considered hybrid turbochargers.

What are the first and last cars on this train ? Braking car/air repeater car ? Beautiful Alcos.

[@PaulGoddard-l8b]

What is the significance of the 's' in the loco number? Thanks in advance.

[@graeme9679]

The s stood for Silverton Rail. They purchased 6 of them, I think.

[@bandittrainz401]

@@PaulGoddard-l8b almost any loco silverton rail bought, they added a ‘s’ in the number. Such as: 44s1 (Ex SA 961) 442s2 (Ex NSW 44217) 45s1 (Ex NSW 3532l) 48s30 (Ex SA 864) 80s1 (Ex NSW 8026) Cs4 (Ex V/line C510, the only operational EMD they had) All the locos mentioned have been reverted to their original numbers, with 45s1 being reverted to its original original number 4532.
