1. In XML G file, one <three_data> tag can replace three tags, <gradient>, <curvature> and <speed_restriction> in the definition of a "gradcrv" data set.
2. XML-ised the F file.
3. To enable 2., duplicate name of two or more substations in XML S file will no longer be allowed. This may mean some mal-formed XML S file with duplicate substation name, allowed in the previous releases, will not be accepted in this release.
4. (binary distribution only) In the Windows installer, a language can be selected from among English and Japanese.

Improvements

1. Added a module to simulate rheostatically controlled railcars (acceleration + regenerative brake by field control).
2. A new class OBESS_Voltage_Controlled, the simulation model for the on-board energy storage system which controls its charge/discharge current based on the present line voltage.

Bug fixes and program modifications

1. Suppressed the use of class StrPrintf.
2. In rf_ffile.cc,  fixed the error message printed by a routine that checks the cycle time of the N file.

Changes in unreleased version 2.6.2a2

Improvements

1. Added the function to print the version number and exit. This is invoked by giving the command line option -o -v to the RTSS executable.

Bug fixes and program modifications

1. Fixed constructor bugs in class OBESS_Voltage_Controlled.
2. In EnergyStorage.cc, fixed bugs that access out-of-range memory space.
3. Eliminated use of class StrPrintf, and removed StrPrintf.hh file.
4. Modified so that RTSS now compiles with GCC 4.5.0.
5. Altered the name of the directory in which object codes are created during compilation.

Changes in unreleased version 2.6.2a3

Improvements

1. XML-ised the G file.

Bug fixes and program modifications

1. Modified so that -Wall option will not yield any warnings when compiled with GCC 4.5.0.
2. In OBESS_Voltage_Controlled.cc, fixed bugs that access out-of-range memory space.
3. Fixed bugs in the calculation of regenerative current in the rheostatic controll module.
4. Fixed Makefiles so that -DSJIS_ICONV option is by default no longer given during compilation.

Changes in unreleased version 2.6.2a4

Improvements

1. In XML G file, enabled copying of data to be given by <gradient>, <curvature> and <speed_restriction> tags from the data given in another data set using their "ref" attribute.

Changes in version 2.6.2

Document modification

1. Altered the license-related documents because GNU libiconv is no longer used by default.

Improvements

1. In F File, nominal_voltage flag is added so that nominal voltage of the DC power feeding system can be changed without re-compiling the software.
2. In F File, any one substation can now have more than one connection points on any one "feedline". This makes simulation of superconducting cables much easier.

Changes in unreleased version 2.6.1a2

Bugfix

1. Fixed a bug so the feed-forward control of on-board energy storage module using the so-called "reference SOC curve" works properly.

Changes in version 2.6.1

Bugfix

1. In nxx_rf.cc, fixed a bug in the processing of attributes of the <gradcrv> tag.

Unfortunately, the environment is not the same as that in 1995, and the PDF file is not exactly the same as the "real" doctoral thesis which must be in the libraries. Also, the PDF file includes some trivial fixes (correction of indexing errors).

The paper is written entirely in Japanese.

The appendix of the paper is the RTSS manual as of 1995 when the Webmaster got his PhD. RTSS is maintained so that, if a user now writes data files and run the program according to the information given in this manual, the program basically runs without problems. The results may differ, because many bugs are corrected after the publication of this thesis.

• Follow this link to get the PhD thesis (PDF, approx. 3MB).

In "Meadow", you can execute M-x compile and use gcc and make that come with MinGW / MSYS by setting Path envariable correctly. However, the Makefiles of RTSS specify that the compilation will take place in a directory different from the directory where actual source files reside, and because of this the M-x next-error function will not work. The gcc and make that come with MinGW/MSYS assume that they run under MSYS, and therefore if the compilation takes place under directory C:\msys\1.0\home\username\foo, for example, they will type out error messages assuming that they are in directory /home/username/foo.

The "Junctions", something similar to symbolic links in the Unix filesystems, can be used when you use NTFS versions 3 and newer. To avoid the above issue,  you can create C:\home, which is the junction to C:\msys\1.0\home.

The methods differ for different versions of Windows. For XP, you must download and install "Windows Server 2003 Resource Kit Tools". The executable linkd.exe that comes with it will enable you to create such a junction. For Vista, you can use mklink.exe that is included in the standard Vista installation.

RTSS is used extensively in university research.

The program was named by Dr Takafumi Koseki, then lecturer at the University of Tokyo. RTSS is officially short for "Railway Total System Simulator". In the inner circle, however, the word also means "Ryo Takagi and Satoru Sone", the initials of the webmaster and his supervisor Prof Satoru Sone, then with the University of Tokyo and a prominent figure in electric railway engineering in Japan.
