Version 3.12, November 2004 Another version where my own contribution is marginal. Steven Masters been at it again and contributed a great many sections: Curved points both tighter (A1tPntM150*/A1tPntM250*) and wider (A1tPnt1500*) than before. 10 degree modular points (A1tPnt10d*) with provisions for a true three way switchs (A1tPnt3w*). New 3 degree and 5 degree frogs (A1tFrog3d*/A1tFrog5d*), 40 degree and 75 degree crossings (A1tXover40d/A1tXover75d). Replacement shapes for 5d points & 10d YPnt and finally also some additional small pieces to fit odds and ends with the others. Please check the track laying page for Stevens directions on how to use these new sections.
New contributor is Mark Hyams with his smooth curves that has been available separately.
My own humble contribution are some new tram sections (A1t5dTramCrv/A1t15dTramCrv). These are also available in dual line tracks (A2t*) and so is the old 30d (A2t30dTramCrv). I've also added a 4.985m straight that is usefull with 90 degree curves to get correct track spacing. Finally inspired by Mark I've noticed the 3000/6000 radius curves looked bad and thus has been updated.´
TSection.dat build #27.

Version 3.11, July 2004
This version I have nearly not contributed anything myself.
Instead other developers have made some contributions I hope you will like.
Steven Masters (NewRoads and now tsection.dat master) has made a number of different frog, crossover and diamond sections for use in the 3d modular system.
He has also made additional curve sections to complemt previous releases.
Andrew Gadd continues the interest for UKN sections and has added some more sections.
Tighter curve sections and a set of 6d modular switches (I did help out a little here).
My own contribution this time is a little odd and more of an experiment.
A set of A1tAngle* sections, tracks angled at 45 and 90 degrees and a Y to go with them.
I don't know what will come out of it, the speedster/trolley track displayed at train-sim.com is one possibillity but I'm sure other uses will also show.
I have made a very small balloon track with them that works but looks strange.
TSection.dat build #25.

Version 3.10, April 2004
New release with many different additions this time (in no particular order).
Couple new crossings (32d & 56d) on request by Bruce Bridges.
A short ukn0_5mStrt on request by Craig Walton.
Updated n1t900r1d and textures by Bill Adams (as released in his DualTracks).
Corrected the manual property of one-piece switches thanks to a note from Mike Deming.
A number of added 1d and high speed curves partially on request by Ian Winfieldale,
some made by me and others by Steven Masters of NewRoads fame.
Updated a1tPnt10d shapes made by Teemu Vehkaoja.
Teemu also noted some LOD level errors in original MS/Kuju shapes that have been corrected.
New a1tDblSlip3d made for Otto Wipfel.
Some corrections to a number of sd-files thanks to a note from Tony Formoso.
A new Portugese readme.txt translated by Rui Fonseca.
Additional concrete shapes by Silvan Schwab, Kai Schadeberg and me.
Some small radius (120r) tunnels on request by Rick Brubeck.
Corrected some animations of n-gauge switches, last of the floating points problem I hope.
Discontinuing the tracklist page, to much work with additions from many different sources.
TSection.dat build #23, the last build issued by David Beach as he now retires.
Thank you David for two years of good service, good luck with your studies.
Steven Masters is taking over the administration of the tsection.dat and I wish him success.

Version 3.9, December 2003
This marks the two year anniversary of XTracks (yes, it's that long now).
The xtracks.tk domain is a success with 50-100 hits a day!
Additional shapes for the UKN* tracks by Andrew Gadd and myself;
60r, 75r curves and 3d modular switches including stub switches.
Switches for the bridge tracks and some additional curves by Steven Masters.
DualTracks by William Adams merged into XTracks distribution.
Slight adjustment of the point animation for standard 10 degree switches (not perfect).
New 750 meter radius curves, both single and dual line.
Changes to the route builders package, splitting textures per gauge.
TSection.dat build #22.

Version 3.8.1, October 2003
Because of a misstake the installer for v3.8 was missing the new shapes.
This is an update of the installer correcting that other than that no changes.
Thanks to Dave Nelson for spotting this problem.
Still TSection.dat build #21.

Version 3.8, October 2003
New one-piece 3d & 6d switches with matching frog sections.
New 79d crossing on request by Dave Nelson.
Dual track curved bridge sections in 250, 500, 1000, 1500 & 2000 radius 5 degrees.
Updated switches for UKN* to cure animation problems thanks to Andrew Gadd.
Changed tsection.dat entry for ukn2t1000r20dTun matching shape.
Updates to the ClearanceDist values to cure problems with UK routes,
Gordon Mackenzie and Pat Dalton helped investigate this.
TSection.dat build #21.

Version 3.7, July 2003
At first this was only meant to be a small maintenance update to cure some visual problems.
As it went along it expanded and became much more:
I have registered an own free domain for XTracks thanks to DotTK.
The new domain is xtracks.tk and there is also a new e-mail okrasa@xtracks.tk. The old e-mail
will still work but the site is moved to generate enough traffic that I may keep the domain.
XTracks now has a logo inspired by Yuri J Sos of Steam4Me.
Made a new intelligent installer for end users, again inspired by Yuri J Sos.
Added a FAQ, route notes and track info to the documentation.
Corrected animation of switches, thanks to Otto Wipfel pointing this out.
Corrected apperance of narrow guage tracks, thanks to Stephen Thompson.
Added curved bridge sections in 60, 120, 250 & 500 meter radius 1 & 5 degrees.
Added an invisble section that can be used for Rick Lamps bridges (see tracklaying).
Included the UKN* narrow gauge sections by Tim Bridge.
Shapes have been revised to correct visual gaps, floating points and texturing for tunnels.
.SD files have been updated to correct shape-names & tunnels and removing bounding boxes.
As a side effect of this there is also a revised A1t2000r5dTun section included.
TSection.dat build #20.

Version 3.6, May 2003
One of the largest updates to date of XTracks, 135 new or updated track sections.
Finally got around animating all the switches and updating the crossings.
I hope Otto Wipfel is happy now as he has been asking for this repeatedly.
Teemu Vehkaoja helped out with the first switches and provided the needed
push to get me finally finishing the animations.
In this release is also added the Roundhouse with back wall opening (a1t30mRoundhThru)
that Martyn Griffin introduced to the tsection.dat but never released.
Got started using gmax for making track sections and made complete sets of
60, 90, 120 & 150 radius curves in 1, 5, 10 & 20 degree sections of each.
Some of these were previously introduced by Bill Adams in his dual track package.
Other additions are 1d curve sections of various radiuses suggested by Dave Nelson.
Those narrow minded will also get their share as I have added a number of new sections.
Full sets of 36, 54, 72 & 90 radius curves in 1, 5, 10 & 20 degrees each.
1 degree curve sections for all the other radius and straigths of 9, 15, 18 & 24 meters.
Again some sections were previously introduced by Bill Adams in his DualTracks package.
Naturally the narrow gauge switches & crossings are updated as the normal gauge.
In this version is also added a Danish installation instruction thanks to
Stig Christensen of team.routebuilders.dk.
Finally the XTracks reference route has been updated showing curve switches
and some of the sections to reduce the complexity when using modular switches.
TSection.dat build #18.

Version 3.5, March 2003
Short straight switch to brake long stretches of track.
Narrow gauge curve by Doug Jones.
Including concrete sections by René Wiggerts.
Additional straights (15, 25, 30 & 40 meter).
Automatic variations of all switches (sans stub switches).
Translated installation instructions.
TSection.dat build #17.

Version 3.4.1, January 2003
This is a minor maintenance release.
Fixes electric wire on high radius curves (4000r - 15000r).
Route builders using those tracks should rebuild the tdb before continuing route building
or they will experience crashes when trying to select those track sections in RE.
Adds missing files for 0.3 meter straight.
No changes in the route builders extra package which remains at version 3.4.
TSection.dat build #12.

Version 3.4, December 2002
Subterrainian sections (tunnels without walls) and scale switches.
Some additional sections for the modular switches to reduce the number
of sections needed, 1d & 2d 500 meter curves.
Updated texturing of tram sections, 0.3 & 1 meter straights.
Roundhouse snow texture added and slight change of texturing (compatible with earlier version).
Updated sd-files for all track sections (XTracks & Kuju) with the bounding boxes removed.
TSection.dat build #11.
Changed packaging to standard edition and route builders extras.
Standard edition includes all files needed by end users,
route builders extras include all textures and documentation.
The update is discontinued as from this version due to this change.

Version 3.3, September 2002
Stub switches in standard and narrow gauge with same geometry as 3 degree modular switches.
Some more straights to ease making ladders with 3 & 6 degree switches.
Includes build #9 of the standardized TSection.dat (needed for the new track sections).

Version 3.2, August 2002
Standard gauge; curved switches in 500 & 1000 meter radius with matching curves,
a few short straights for modular switches.
Narrow gauge; double track curves in varius dimensions, tramway switches and
some short sections to help when laying out track including a short dual gauge track.
Corrected track profile in the track making document (rail width corrected).
Includes build #8 of the standardized TSection.dat (needed for the new track sections).

Version 3.1, May 2002
Minor maintenance release with a new lift bridge by Teemu.
New shape files for the scissor, 5 degree Y and 3-way switches.
Includes build #3 of the standardized TSection.dat (needed for Teemus new bridge).

Version 3, May 2002
Another major revision, I had thought this to be a minor update but new ideas on how to layout the TSection.dat file meant this release to be a major step forward for all wanting to use add-on track sections. This version replaces earlier versions and unfortunately you need to update your routes to be able to use it. Good thing is the standard routes should work as they come from the CD and any downloaded route not using add-on track sections should also work as is. Routes built with XTracks 3.0 should work happily along routes built with other add-on track packages as long as you use the standardized TSection.dat.

News in this version:
A new tighter set of modular points. Tram switches with very tight radius.
Special bridge rail sections with guard rails and without any track bed.
Single track level crossings and a 62 degree crossing.
Corrected many shapes for lighting and shadows.
Horace is now his own distribution.
Including a number of bridges by Teemu Saukkonen (Enocell).

Version 2, February 2002
Added roundhouse section, more curves, modular switches, crossings and tunnel switches.
The switches are somewhat simplified as the blades are not properly animated but they are
fully functional and look good enough for the moment. Anyone wanting to improve on
their looks is welcome to do that, updating the package with new shapes is simple.
Narrow gauge tracks also got the modular switches and some more curves.
Added Horace to address problems in first release concerning dynamic tracks.
Corrected some default paths for right hand switches and detail level for turntables.
Changed path for a2t2000r20dTun to match shape.
Removed a2tXoverEnd and us1Rd2l1000r10d since they don't work anyway and there are other options available.
Reserved more space for future track sections and included directions on how to update a route to use XTracks.
Changed this documentation into html.

Version 1, December 2001
First version.
