Station Objects will be added in Version 3. This morning I used
the C751B to test my route. LOL! And the psds I am now using are
the EWL's psds (6-cars - C151, C651, C751B).
Tell you what, go to the floor.csv, and you can roughly see the
-11X+.XX (Negative 110 + meters). That is how long it extend
backwards. (The history of FHPSD comes where Willis install the
first 4, and only 4 PSD in his CGA, so I do it simple way which
just extend it backwards). You will need to divide into 2
(Approximate), which gives you like 50X or so, that is where you
need. Look for the direction, and check for the 12nd PSD and you
should have a hint or so.
Regarding 3 cars C751B (or any other trains), it is
possible.
Go to the specific train folder, find the extension.cfg
And you will see something like this
[Exterior]
0 = cars\3237.ANIMATED
[Car0]
Length = 23.5
[Exterior]
1 = cars\1237.ANIMATED
[Car1]
Length = 23
[Exterior]
2 = cars\2237.ANIMATED
[Car2]
Length = 23
[Exterior]
3 = cars\2238.ANIMATED
[Car3]
Length = 23
[Exterior]
4 = cars\1238.ANIMATED
[Car4]
Length = 23
[Exterior]
5 = cars\3238.ANIMATED
[Car5]
Length = 23.5
Each [Exterior] means the exterior object (we name
it by train car number) and [CarX] refers to the car number,
starting from 0 (Any programming language will tell you
that index starts from 0).
See the difference. This is why certain train car between the
gaps got difference and I have to research and trial and error
until it fits, like now. All number are in meters. (Obviously, you
are going to keep Car0, Car1 and Car2.)
