I bought one too.
While i love green locos, alas three headlamps and $200 difference made it easy. Plus, as i had an earlier all black IVk, 2 chuffs, , i decided on ......uniform appearance.....quite odd for my love of livery variations.
As i am still running analogue, i miss the start up whistle.
The sound on mine is nice, my first four to the turn lgb loco, and it really is great.
Mine does not seem to have the most sensitive subtle smooth start up throttle response, but is fine. With four chuffs, i seek that nice slow tempo increase. Nada.
My sound, is, odd, however. It seems , from time to time, to have some sort of resonance portion cut out and then return, almost as if backing off the throttle, and drifting. Still get four exhausts, but less bass or ???.
To my yank eye, these are ...wierd, with mirror cylinders, yet, i love their unique appearance.
Mine too smokes nicely. And, i can park it lights and smoke, low voltage. It does not have a cab switch like the previous lgb versions.ie no motor off, lights on.
I have to add, after attending a marklin digital presentation at a big denver train show, for their latest, digital system, i was put off. Clearly geek to geek speak.
Sadly, i was ready to go digital, and willing to refit half of my too many locos, etc. as the inclusion of mfx in new locos is tempting. I miss so much in operational features running analogue.
But mfx is designed, as i understand, not to be
compatible with other brands, seemingly overly complex, pricey, and, likely to become obsolete, with the new tablet sized controller.
And, I think i dont have the german mind set for automated train operation. The new system can set routes, turn outs, stations, etc. but even the techs were having issues doing this easily.
. Yoiks, my geezerness is showing, i guess.
