Today we have released an update for the Union Pacific FEF-3. This update contains the following changes: 1. Stack smoke is more dense. 2. Mars light can now be removed from the HUD version. 3. Missing bump-map texture recovered on the main drivers. 4. Two FEF-3 can now be double-headed (AI helper must be a HUD version). 5. Improved the graphic equalisation (bass versus treble) of the chuff sounds. 6. Overland striping is now correct when the smoke deflectors are removed. 7. Fixed the association of blow-down valves to sight glasses in the HUD version. 8. Whistle sound now fades out properly when the cord is released from inside the cab. 9. Removed the embossed shield ("Union Pacific 844") from the cab floor of all except the striped, white-walled version of 844. 10. It's now possible to put blanks in the train board slots (# means a blank). 11. When using the HUD version of FEF-3 for AI-only consists the driving wheels no longer lock up. 12. Halved the time for the back pressure to drop (so it's easier to shut off steam). 13. Increased the clanking sound at low speed. 14. Engine brakes now correctly apply force in proportion to the brake cylinder pressure shown on the gauge in the cab. 15. Improved throttle response, with pilot valve simulation. 16. Improved simulation of the behaviour of the back pressure gauge. 17. Dynamo can now be heard winding up and the dynamo running loop is smoother. 18. Left cab door stays open when switching to outside view and back to cab view. This update will be 169.3mb.
