The next new feature for O scale 3 rail diesels???

I've been enjoying the steam related thread.  How about one for diesels?

I would like to hear a high rpm sound starting from a dead stop and then the rpm's ease off once under way at speed.  Just the way I remember how it sounded riding in that first coach behind the big Alco Century's on the Long Island.

Original Post

I liked the idea about the bearing caps spinning on another post. I think anything capturing better detail adds to the enthusiasm.

MTH did change the behavior of their diesel's smoke units.

Watch the smoke volume go up with the engine's rpms.

" on Sour mash and cheap wine " ??

Why go back to DCC when I have DCS!

More lighting, including step lighting - several side panel opening maintenance doors with a modeled three dimensional engine behind the doors. A down side to more doors though could include increased risk for breakage.  More LED lighting, though, is an easy feature to add.  Lionel is on the right track with their self centering pilots.

I drove to Salt Lake City for the Thanksgiving Holiday and on the way out saw Union Pacific running freight in western Wyoming at nearly 80 mph.  It was cool to notice all the side lighting on the 3-4 locomotives.  There is a lot more to lighting than just headlights, ditch lights and cab interiors.  N Scale modelers are adding step, safety and inspection lighting to diesels.

How about eliminating green markers on the front of diesels. I'd take white maybe, red rarely. And allow us to turn them off. Not a bad option for steam as well.

John, I'm with you on the flames from the stack.  A lot of the old F7s on the EL in the last days went through my town lighting up the night sky.  

Step lighting if done right (not overdone) would look good.  

The random "spit" of air dryers when stopped would add to the RR atmosphere. 

This is fun!

You can do that now with m t h  docs......

It better be a Cast iron body, the fire would melt a plastic shell.     also a model that has a turbo, seems to me the turbos are the cause of most of the fires still to this day on the 1:1s,  if you believe the Youtube videos.

Also if can be used as a cigar lighter. 

Good idea.

I know where I have been, I know where I am at, I am hopeful I know where I am going.(The devil and God are talking it over).

I just installed an ESU LokSound decoder in an Atlas GP60 and once the start-up sequence is initiated the locomotive goes from idle to about the 4th notch. Once it starts moving the rpm's drop to idle then slowly increase as the throttle is engaged.

Never argue with a fool, onlookers may not be able to tell the difference.

ESU Loksound is awesome.  Sounds exactly like the real thing.  Would like to see something like that for 3 rail.

I did see sparks coming out the stack of UP 6936 idling at the Amtrak Station in Houston.  And when it left it was LOUD!

Gosh, yes. class lights are almost always off. Too many locos look like Xmas trees.

"Fixed pilots on higher end models"

At these prices, an easily, reversible frame-mounted pilot (separate piece or a spacer, etc, for use with the "standard" one) should be a no-brainer. Wait - Atlas does that...! And I put mine on my NYC F2. So - no excuses. (Same thing with the tiny-wheeled steam loco 4-wheel pilot trucks - big curves usually don't require this compromise as often or to the same degree; I have 072 curves, as many of us do. For $2K, could I have a second truck, or optional wheel sets with an easy swap design? Really?)

I think I was indirectly involved with this failure mode-think late 70's

Today both GE and Westinghouse semiconductors merged into Powerex 1986

We supplied and still make rectifier stud mount diodes with a solid copper internal cathode rod

When there was a electric short in the locomotive the Westinghouse diodes (150a or 275a) did not open and somewhere in the GE circuit you got flames

The GE diode design uses an internal flexible stranded cathode rod which when shorted would open- a fuse
