Locos running light, at crawling speed

Hi All.   I live in Peckham( dwell in Peckham) really close to a Railway Viaduct, carrying freight right through the day and night, which is great for an enthusiast. Like me, and I have noticed that when the Locos are running light, especially " the Shed type" there is a characteristic dry axle sound, which is hidden when loaded or motoring.This is a sound that seems to be missing from Decoders? Please correct me if I am incorrect.All the best. Kevin

You maybe correct Kevin in that sound missing from decoders but I would guess not too many model rail layouts would run locos light that often, to be concerned about that sound missing.

Hi Ron.  Thank you, it was just an idea, but ,thinking about it:hmm most modern Locos would not move without power.Whereas " 40 odd years ago?" I had an old Hornby die cast ,of course no sound, but that one had a ringtield motor,
and after I would shut off the power, it would roll to a halt. All the best. Kevin

Hi Ron.  Even in the U.K. It is sometimes necessary for National Ral to run trains io one direction with multiple Locos ,and if they did that everyday , without returning them, there would be a lot of Locos at one end of the line.
And to save "manpower " Locos re often run back in multiple .    Kevin

Hi Kevin,

Good programmers will make sure that the engine "runs light" when easing off the throttle. (It all depends on the skill of the programmer). I know my Truro" ESU from Howes goes into valve clack and no chuff when decelerating or when the throttle is eased off. My ESU diesels also notch down when slowing down. But that's standard anyway (although usually user modifiable). Don't forget to set the momentum, otherwise a sharp deceleration is likely to stop the engine dead.Not quite what you usually want.

Hi Nigel.  Thank you , when I said "Running Light", I meant without a load. Usually a Loco returning to depot.All the best.   Kevin
