Never make such assumptions
I haven't got that far (the stuff in the "newer" panel isn't implemented yet - they've just seen some rather ugly hacks applied
![Smile :)](./images/smilies/icon_smile.gif)
), and it might be a little pointless in the case of some wagons where you can't actually see the load level in RL anyway (e.g. the HTA coal truck - I might pinch the current images for classic HAA coal trucks, which look similar to the ones in the game). Where it is appropriate (i.e. when uncovered cars are used - possibly with a tarp-enhanced graphic
![Wink ;)](./images/smilies/icon_wink.gif)
), then I might see about gradual loading - many will probably be stolen from where they already are. The main exception here is the new concept steel cars, which will deomnstrate three states, with {0,1,2} batches of steel product (plate rolls or wire reels) in the slots.
Another thing - the current in-game sprites are in the main GRF file. I'm still trying to get my head around the "replacement" machanism.
Next task, prepare some concept graphics for passenger/mail cars. This might take some even more clever fakery.
At this point, might I thank those peope that have demonstrated interest, without which I'd have probably not bothered getting past the proposal step.
