Quote from: VaclavMacurek on August 17, 2011, 02:44:45 PMI began creation of new tracks - at first I prepared one for speed 280 km/h - but it is not finished - because it needs better shading of bed; I think that next would be track for speed 400 km/h - without classical sleepers. Other tracks should have shorter sleepers (current size was chosen for test).I don't know what software do you use, but I am ready to share my work with you - to shift work on those tracks ahead.
Quote from: fabio on August 17, 2011, 03:36:04 PMI have a different speed plan:60 - 80 - 120 - 160 - 240 - 320 - 400 km/h
QuoteA good idea, if you feel like sharing the work, is to keep the track (ballast+sleepers+track) the same for a given speed and as similar as possible to the others.

QuoteAs the eras change (25 years periods), tracks will change their scope. Sume will survive, other retired.

Quote from: sdog on August 18, 2011, 12:12:47 AMFabio, since those tracks have been finished for such a long time, perhaps you should do a partial release, of the tracks and some of the finished tunnels/bridges. The old bridges can work as placeholders in the meantime. This would make sure it doesn't slip out of memory of others, who in turn would perhaps do the same work again.
Quote from: VaclavMacurek on August 18, 2011, 05:40:00 AMIt is not good if in menu are too many tracks ... but still somewhere are tracks built only for speed about 80 km/h
Quote from: VaclavMacurek on August 18, 2011, 05:40:00 AMIt seems too high to me for this age - I would like to suggesting shifting of these two tracks by one age (those 25 years)....Only few trains could go by this speed - but technically they went only about 120 and 130 km/h....I am sorry for a little amount of being upset and eagerness for knowledge - but could you tell me which trains could go this speed? If I know well, the first trains that could go this speed appeared at least ten (or more) years later...What train can go this speed? (I know that in game there are few trains but ...)
Quote from: VaclavMacurek on August 18, 2011, 05:40:00 AMYes, it is very good idea - to let tracks change as time goes. But most important it is with tunnels.
Quote from: VaclavMacurek on August 18, 2011, 05:40:00 AMIt would be good if you would download prototype (link is few posts above) of my track, see it and say if it is usable by yourself....Yes. Thanks. It means I can export my track per parts - for easier improves.

Quote from: PkK on August 29, 2011, 10:26:17 AMI would recommend to use a "Feste Fahrbahn" (don't know the Englisch term) in staed of gravel ballast here. "Feste Fahrbahn" i sused on many high-speed lines these days. Even the French that went with gravel ballast for a long time are now using it for some of their new high-speed lines (and other countried, like Germany have been using it for some time). A typical picture can be found here:http://de.wikipedia.org/w/index.php?title=Datei:Feste_Fahrbahn_FFB%C3%B6gl.jpg&filetimestamp=20050917170741
Quote from: PkK on August 29, 2011, 10:26:17 AMAt such speeds, simple tunnel portals won't do (for single-track tunnels, which have a lower diameter than the double-track ones). You'll get a tunnel boom, like when firing a firearm, so the tunnel portal needs the equivalent of a suppressor.This results in unusual-looking portals, like these:http://www.eisenbahntunnel.at/bilder/tunnelportale/13002/wienerwald-west-2009-09-0835.jpgOr, alternatively extra air outlets near the portal, like here:http://www.tunnel-online.info/de/artikel/bildpopup_1097687.html?image=1http://www.tunnel-online.info/de/artikel/bildpopup_1097687.html?image=3

Quote from: fabio on August 29, 2011, 10:37:04 AMVery interesting, and also very new to me. I know that today many long base tunnels are bored with two tubes. Also, the air shift of two trains meeting in a double track tunnel at these speeds can be disastrous.I'll try to see how can a longer portal and some air flow outlets can be added to a single tile Again, thank you very much for the ideas.
Quote from: Zeno on January 17, 2012, 03:43:49 PMAFAIK the highest commercial train in europe were the spanish Siemens Velaro trains, which were certified for running at 350 km/h. I think the newest french TGV (AGV) was certified 360 km/h, but not sure. I know that the chinese hst were really fast, but I can't say how much is "fast". Definetly, I'd say 400km/h is a good limit, unless we find a good reason to use a higher value.
