I have noticed that AI steam locomotives don't chuff or makes sounds while connected to coaches or wagons. However, they do chuff while not being connected to anything and running light. This has been the case since steams locos first come out. Needs to get fixed.
If on AI it's a known bug which seems unlikely will ever get addressed as DTG have abandoned any further work on steam traction in the game.
I've already done a support ticket on this annoying AI bug. It is however a known one as it's something that's been around since SoS was released back on TSW2 so like OldVern said there's a high chance it won't be resolved anytime soon.
It's been like that since the release of SoS. Pretty safe to assume after 2 years that DTG don't care and won't be fixing it. They've already said they won't be making any more steam locos, or adding in the things that they promised were going to be added when they released it originally.
I'm still waiting for the silently removed blood-and-custard coaches from Spirit of Steam. I would have loved to see the randomly generated formations!
That would of been amazing if they had done that. But unlikely they will do that as they have not fixed the AI smoke and sound bug which in itself is also unlikely to get fixed.
I haven't checked recently, but I believe they are there in the scenarios. I hope they haven't gone from there.
Sadly all AI will not chuff or puff out smoke while connected to a train. Its been a bug since the beginning and they have not fixed it in 2 yours.
Sorry, I was referring to the blood-and-custard coaches. I am sure AI trains don't chuff in scenarios.
