Hello, I would like to ask for the correct handling of the Class 76-bX... Weight Transfer Switch: 1. - for what I use that switch ? 2. - when and how do I use that switch / procedure ? Otherwise the old maid works perfectly fine for me ... Great old locomotive for TS classic !
To get the loco moving, turn the switch on. If you're accelerating and decide to go into weak field then turn the switch off. However if you're using parallel then keep the switch on. When wanting to use regenative or rheostatic brakes, turn the switch off.
Hello, thank you for the info... I never used the Weight Transfer Switch so far. I always did start the Class 76-bX with Weight Transfer Switch in OFF position. - that works fine. Now I tested to start the Class 76-bX with Weight Transfer Switch in ON position.. The only difference I could notice: ... acceleration is a little bit faster ? - green control light shows ON. When I understand the function of the Weight Transfer Switch right, I just use the Weight Transfer Switch in ON positon for starting the Class 76-bX ( heavy train, hill, gradient ...). As soon as I reach 16mph or 33mph, I use the dynamic brake system to accelerate the train for route speed ( and control the route speed ); of course Weight Transfer Switch in OFF position.. Right ?
From the DTG Class 77 (EM2) manual Weight Transfer (Class 76 only) - This has the effect of reducing the torque supplied to the lead motor in each bogie which provides superior traction. However, this ceases to be effective at around 21mph, at which point switching off Weight Transfer will allow full power to be applied to both axles. (Only operable from the cab view) Further on p 13 I think it explains the rationale of the WTS.
https://live.dovetailgames.com/live...icle/woodhead-in-blue-a-class-76-introduction "Weight transfer on the bogies is modelled, this is a fairly unusual trait of the 76’s due to the unique way the bogies are designed; while there is a load on the drawbar (which gets naturally worse during acceleration), weight is transferred off the lead axle and onto the rear axle on each bogie, meaning the lead axles are much more likely to slip. Of course, the locomotive also features my standard adhesion model making driving in adverse weather conditions even more challenging (use of sanders is advised!)."
'749006' , what a name... ? - thank you very much for the extra info by E. Fisk; highly appreciated ! Well, I love the old fashioned Woodhead 'ProRange' ladies... - especially the Class 76-bX and 08 are wonderful. When I drive the Class-76-bX, I feel the old atmosphere ... This old maid shows up with charme and nostalgia. P.S. ... till the unexpected will cross your way !
