The all new Big Boy/4000 series locomotive by Smokebox now at the Steam store.

This is the most advanced steam locomotive DLC in any train simulator.

Just heard of smokebox last week while watching videos on Big Boy and the upcoming new build T1.

Watching his vidoes pretty much sold me on Train Simulator.

This is by far the most detailed locomotive for any simulator. If you wish to fire and drive yourself you have that option, but you can turn off the game's auto fireman and use the provided one by clicking on the fireman's seat then you can concentrate on driving. If you want an easier way then you can use the F4 HUD to drive and use simple controls. Everyone can drive this locomotive one way or another by using any combination of the driving modes. You guys that drive steam for real will enjoy this. Those of you who just want to sit back and watch it has a auto driver feature. You can sit in the cab and watch everything work or use the external camera to watch the valve gear action. Watch the videos from the links posted. $24.99 US is more than fair for this quality of locomotive. This has the highest quality of modeling, sounds and physics. Comes in HD and an SD mode to match your systems specifications. View the manual here: https://cdn.akamai.steamstatic.com/steam/apps/1515065/manuals/Smokebox_-_Big_Boy_Manual_-_EN.pdf?t=1622120549

I'd like to keep everyone updated on the Big Boy post-release activities:
1. Some bugs are being investigated and I expect an updated hotfix to be available this week. I'll post it to Dropbox as soon as it's ready, so that if it's urgent for you, it can be downloaded and installed while we wait for DTG to release it on Steam.
The bugs addressed by the hotfix are:
Derailment of very long consists - a change to the coupler damping should solve most of the derailment problems. There are some special cases where the derailments are not the fault of the loco or rolling stock but appear to be a bug in TS that happens with very long trains that follow a route determined by the Quick Drive dispatcher. It's not clear if there is any solution for those. You might just have to select shorter consists for particular Quick Drive scenarios if the longer ones derail going through switches.
In free roam, prevent the steam chest from filling before the loco has been selected by the player (this bug was causing the free roam loco to lurch forward as soon as the reverser was moved forward).
Remove the obsolete pop-up message about switching between "easy" and "difficult" modes.
Pilot truck wheel rotational speed corrected (they appeared to be rotating too quickly).
Chuffing sounds between 10 and 40 mph.
Live injector sound attenuation outside the loco.
2. I'm also making a series of short tutorials to explain some of the nuances of the loco in more detail (the brakes in particular). However, I also recommend FanRailer's tutorial videos - well worth watching!
Thanks to everyone who has already purchased the loco, and to the rest of you, I hope you'll consider adding it to your collections

Like others, I have been awaiting the release of this awesome project. But if it has been released, I can't fine it. Not surprised given DTG's brain dead marketing competence. It's a wonder they can sell anything. If it's available, where do I find it? Don't see it at the Steam Store and only other link is a YouTube collection of clips.

If it has been temporarily withdrawn to fix bugs, someone should say so. If it is at the Steam Store, please tell me where.

Does it work for you?

[hygoose]

Got it. Thanks. Looking forward to thrashing this beauty.

I've posted on my Facebook page (https://www.facebook.com/Smokebox-132794016882582/) a link to the June 1st hotfix which can be downloaded from my Dropbox. It's for anyone who'd like the bug fixes quickly, ahead of them being released and distributed officially via Steam.

Is it normal for the regulator percentage on the F5 HUD to change depending on your view? It seems the frame rate has a big impact on the steam chest script, so to avoid blowing the safety I have to adjust the reverser if I change views. It's especially erratic in the cab view, simply looking in a different direction can cause the F5 regulator reading to change from 97% to as low as 65% and everywhere in between. Can anyone else repeat this bug?

(PS everything else is absolutely fantastic. I tip my hat to you Smokebox, somehow you managed to outdo yourself with this one! I've wanted this for a long long time, and now it's here it's better than I could've imagined)

I have been swapping this and the included railstock into older scenarios for Sherman hill using loco swap and TS_Tools. What a difference in performance and aesthetics. A must read is the suggested in-game settings in the manual to get the best looks and performance. I can't stress this enough to read the manual.

Thanks Spitfire, really glad you're enjoying the loco :)

What speed is the loco doing when you see these strange changes in the "regulator" percentage? The reason I ask is that the algorithm changes from a very detailed one to a less complex one at around 11.2 mph, because at that speed the pistons are going too fast for the sampling (which depends on the framerate) to keep up with the speed of the individual valves opening and closing, so it switches to something that averages instead.

Repaints for some of the boxcars without road names that come with the Big Boy/4000 pack. https://www.dropbox.com/s/7hcvea9ca6t2hv8/Smokebox%20CO%20WM%20Boxcars.7z?dl=0
