Class 20 Helper Locos

joea1 · Post by **joea1** » Tue Sep 19, 2006 7:55 pm

Hi,

Just a quick question - what do I need to do to an ENG or SMS file to give Helper locomotives full sound? I've seen cabcam mentioned, but I'm not certain what exactly I have to add to the file.

Eg If I'm double heading a train with a 37 leading and a 20 behind, how would I get full sound out of the 20 as well?

Cheers!

Normally if you take a normal version of the loco and add it to your consist you should have all the normal external sounds. Have you got sounds ok when you use it on its own ? It may just be that the sounds of the 37 are louder and drowning out the 20

Yep if the 20 is leading then all sounds good.

But if a 37 is leading the 20, all I get is the 20 sounding idle

. I'd like it so the 20 would sound the same as it would if it were leading

. Same if I have 2 20s top and tailing a consist.

Hmm... curious. You aren't using an AI version of the 20 are you? ( eng file starting with a #). The AI version may well sound a bit like that (not tried it ) but the normal running version shouldn't. What happens if you put the 20 at the rear - does it sound ok then as it passes or is it still idling?

Im afraid i dont have any other ideas - maybe another sage may

Nope - definitely using the same one every time. If I put another 20 on the back, it still idles

.

I remember a while back, Making Tracks published a solution to sound not coming from helper vehicles. Since I tried that, I get motor noises from each motor coach from units, but every loco - and DMUs for that matter - still only work with the first coach - the rest idling

. Would it be worthwhile looking that up and increasing the value which they suggested?

Not sure - might be worth a try. Might also be worth asking a moderator to move this thread to the Sounds forum where you might have better luck - not everyone reads this forum

I think its a known issue with MSTS.

I think it comes down to the fact that most sound setups are based on throttle position for sound.
Whereas in the situation described the loco 'throttle' IS at idle. (although it may be helping to power the train etc...)

I think you can design a SMS file which uses speed as the trigger, so things like the HST rear power car kind of sounds more like its doing something.

Depends which soundset you're using.

If its kiegills class 20 soundset, it comes with a specific AI SMS file you need to alias your loco to. I'd also create an AI version of that loco using route riter.....

Ok cheers for the help everyone, I'm currently trying it all out.

Out of interest, do you normally get full sounds from every loco in a consist?

If the locos are set up to AI SMSs, yes.

Ok - I now have full sound coming from both 20s top and tail - cheers for the advice - wicked soundset too!

The AI sounds are definitely speed dependant rather than throttle dependant though.

e.g at 70mph, no throttle, the 20 is making a racket, but at 10mph, full throttle, its making barely any noise.

Dave, are you saying that this means that MSTS cannot support the idea of a helper loco applying throttle as well as the leading loco? Despite power + smoke coming from the helper loco(s)?

As I understand it yes.
I assume that it applies power as per the player loco throttle application, but I don't think the sound system picks up this throttle.
