Open Rails 1.1 released!
The Elvas Tower forum plays a major role in developing Open Rails but has been closed to non-members following a dispute. We can now report that some of the Open Rails sub-forums are open again.
Peter Newell has just released (June 2105) the Great Zig Zag Railway, a steam route for Open Rails v1.0 (this 120MB download requires no other files).
Open Rails first demonstration route Demo Model 1 has been published.
Dekosoft Trains has added locos exclusively for Open Rails to its range. These are GP30 diesels taking advantage of our 3D cab feature.
The legacy graphics-heavy web site has been replaced by one based on Bootstrap which is both easier to maintain and suitable for phones and tablets as well as PCs.
You can still see an archive of the old site.
An installer is now available, so Open Rails and its pre-requisites such as XNA can be delivered in a single download.
Open Rails currently uses DirectX 9 and, although this is not the latest version of DirectX, hidden away inside is a method for reducing the number of "draw calls" which the CPU makes to the GPU. Fewer calls mean higher frame rates, smoother motion and the capacity to handle more detail.
The technique is called "hardware instancing" and allows identical objects (e.g. trees in a forest) to be combined into a single draw call. The work is transferred to the GPU which copies them as many times as necessary and usually has spare capacity.
You can expect some increases in frame rate, especially on routes with many identical objects. To turn this on, tick the checkbox for
Options > Experimental > Use model instancing
Open Rails becomes available in additional languages, initially eight including Chinese.
A schedule of trains (or timetable) is nearly impossible to arrange in Microsoft Train Simulator as AI trains don't adhere to booked station stops. In Open Rails, the situation is better but an activity with a player train and AI traffic is still very different from a timetable.
Work has now begun on a timetable element which is an alternative to the usual activity. The timetable will contain all the details needed for each scheduled train - path, consist, booked stops etc.. Conventional activities will continue as before.
Also there is no longer any distinction between player train or AI train - any train in the timetable can be selected as the player train, the others are operated by a remote player or by the simulator.
Fog is developed from just softening the horizon into a realistic effect which users can fully control.
