After seeing some videos from people player TF i suggest to developers and some players (some of them are repetions):

• try to reach realism on tracks: curves, staions layouts (juntcions, signals, etc.),
• try to undestand how real railroad works,
• time shoulb be more controled by players,
• xcrossings should be choosen (with / without barriers, with / without lights,
• light signal should have 3 colours, at least: red, yellow and green.
• junctions more realistic and with levers (with motion when we are seeing very close).
• stations should have more lines (8?).
• stations with passangers and cargo functions at the same time like and until the end oh xx century (+-).
• lines: it will be possible to cross lines.
• inversing trains direction: for steam locomotives must have a turntable; for electric and diesel locomotives must be possible to disengage and engage locomotives (of course and with same space and juntions to do this kind of operation).
• acceleration and breaking shoulb be more realistic.
• the trains depots shoulb have more length.
• space  / space between villages souhld be greater because trains trains need space for des / acceleration and for shunting.
• should have warnings when there are circulation conflict between trains.
• develop some movement when cargo train are loading / unloading with some cranes or other type of funciontal structure. It should visible at some camera distance only in order not to over use the AI.
• should have other kind of industries and structures like: harbours, airport, containers stations specific industries (cars, cement, etc).
• the possibility to choose the industries locations.
• whe we are using buldozer we souhld earn some money because we are recycling …

Now the things I like:

• freedom to locate tracks.
• freedom to locate stations.
• freedom to build lines (train, buses, truck and tram lines).
• 3D realism of the objects.
• management system of our money.

Cheers, T.
