Bugs

• Interacting with the shovel on the Flying Scotsman doesn't stop coal shovelling.

Guard mode

• There probably won't be any passengers until you stop at the first station (I think this is a core issue).
• Sometimes it wants you to close all the doors yourself.

Changes

• Enabled the extra HUD elements showing coal and water, and made them functional.
• Water level is no longer infinite and can be used up.
• Live & exhaust injector water valves, live & exhaust trim valves, live & exhaust injector steam valves are now usable (unfortunately they are not animated on the 4F).
• Animated the coal level in the tender, reflecting the amount of coal left.
• Added ability to toggle coal shovelling (click on the shovel, the firebox doors must also be open),
• Added ability to see amount of coal in the firebox (open the firebox door).
• Added ability to see amount of coal in the tender (open the coal door).
• Added ability to see the water level in the gauge glasses.
• Added ability to see the water level in the tender.
• Added ability to load and unload anywhere (hold the engine start stop keybinds).
• Added ability to toggle infinite coal/water (hold the aux battery power keybind).
• Added driver assist notifications for low coal & water, handbrake on, boiler full.
• Added ability to disconnect and reconnect tenders.
• Increased emissiveness on the headcode and cab lamps.
• The cab lamp can now be controlled with the cab light keybind.
• Added ability to toggle festive decorations using the coach lights keybind (they will only show up if you have West Coast Steam Railtour, and something from it is loaded into memory first).
• Locos will now start with the live injector, trim valve and water valve open.
• Locos will now start with the handbrake on, if it is a light loco.
• Increased live injector effect (the exhaust injector doesn't seem to do much).

• Jubilee & 8F - Windows now use the improved rain effects.

Coaches

• Added guard mode (there aren't many services it works on for the Scotsman, West Coast Railtour and Training Centre versions).
• Added ability to lean out of the guard compartment windows.
• Fixed collisions in the FK so the compartment light switches can be used (the bulbs don't glow though).
• Stopped the doors from locking themselves when moving.
• Windows now use the improved rain effects.
• Added ability to toggle festive decorations (they will only show up if you have West Coast Steam Railtour, and something from it is loaded into memory first).

• Flying Scotsman Mk1 & Mk2a - Added ability to toggle FRED/EOTD lamp.

Flying Scotsman

• Water level test valve in the tender made functional (unfortunately it is not animated). Open it and then mouseover the pipe markings.
• Added usable angle cocks.
• Fixed the fireman's seat, so you can sit in it.
• Fixed the rear coupler, so it can't couple to hook couplers when the drophead is up.
• Fixed the tender connection point for water hoses.
• Reduced the driver assist notifications.

Notes

• If either the firebox coal level or boiler water level gets too low the service will end.
• To allow water into the boiler, make sure the water valves on the tender, and the trim valves & steam injectors in the engine are open.
• To shovel coal, open the firebox doors and it should happen automatically (you can turn this off by pressing on the shovel).
• If you want to load or unload the tender, hold down the keybinds for engine start and stop.
• If you want to have infinite coal and water, hold hold down the keybind for aux battery power or a few seconds.
• The AI doesn't know how to use the injectors with automatic firing.
• The tender water level gauge of the Flying Scotsman does not work properly. Although it is animated, it seems to show the value in litres instead of gallons.
• The trim valves don't seem to actually adjust the flow rate of water, they just act like they are either on or off.
• The exhaust ejectors don't seem to do very much.
• Won't be compatible with any mods that modify the same RVD, RVM or RVV files, since one mod will overwrite the other.
