Moving bridges

 

This Chapter deals with Moving bridges only. Static bridges have different rules and are described in another chapter.

 There are three types of moving bridges. The first two should work with all versions of FS while the third only works with FS2000. I am sure that users of FS2000 will only use the third type.

A) Straight moving rails with a static rail above.

You can use these macros in FS95/98 only. The macros behave like normal dual rails between end1 and end2 and a static single or dual at height 28 between ends3 and 4. The naming convention is M1Br2nll, where n =1,2 is the width of the upper rail and ll is the length in 10m units. Here you see M1Br2215, a 150m moving rail below a 50m static rail.

All moving straight rails are called with the same parameters:

Parameter Value Meaning
%1   Geographical width
%2   Geographical Length
%3 0 Rail is placed on the surface of the FS terrain.
  Unequal 0 Absolute altitude of the rail above sea level in m
%4 0.250 Scale. Should always be 0.250.
%5 Orientation Orientation of the rail on the terrain (0 = south-north direction)
%6 0-7 Wires, Pylons and lamps:

0 no wires, no night illumination

1 wire, no night illumination

2 wires, simple pylons, no night illumination

3 wires, massive pylons, no night illumination

4 wires, massive pylons, lamps

%7   Train # for primary timing. If negative, trains run left.
%8   Timing of primary train in form ssnn

ss = Time the train enters the macro southbound

nn = Time the train enters the rail northbound

%9 0-4 Power pylons for the upper rails
%10   Range in m

Rail is visible if within range. Typical value is 7000.

The last digit is used to encode the rail texture.

%13   Timing of secondary train in form ssnn

ss = Time the train enters the macro southbound

Nn = Time the train enters the rail northbound

If %14=0 the train %7 is displayed twice per cycle

%14   Secondary train

 

These bridges do not support extended light illumination because I assume they are not used with FS2000.

The following macros are available:

Length \ upper rail Single upper rail Dual upper rail
100 M1Br2110 M1Br2210
150 M1Br2115 M1Br2215
200 M1Br2120 M1Br2220
300 M1Br2130 M1Br2230
400 M1Br2140 M1Br2240

 

B) Big river bridges for FS95/98

For all earlier versions of FS the transition between rails for moving trains have to be at ground level. No way around. The bridges for FS95/98 which have a moving train above something therefore consist of a flat part, a ramp to climb to height, the bridge itself, a ramp to get down again, and a flat part. This makes them very long and unwieldy. Nevertheless they are the only way for FS95/98 to cross above rivers or roads. Here you see M7br2h50.

The following macros exist:

Length  
900m M6br2900
1500m M6br2f00
1750m M6br2h50

The calling sequence is as follows:

Parameter Value Meaning
%1   Geographical width
%2   Geographical Length
%3 0 Rail is placed on the surface of the FS terrain.
  Unequal 0 Absolute altitude of the rail above sea level in m
%4 0.250 Scale. Should always be 0.250.
%5 Orientation Orientation of the rail on the terrain (0 = south-north direction)
%6 0-7 Wires, Pylons and lamps:

0 no wires, no night illumination

1 wire, no night illumination

2 wires, simple pylons, no night illumination

3 wires, massive pylons, no night illumination

4 wires, massive pylons, lamps

%7   Train # for primary timing. If negative, trains run left.
%8   Timing of primary train in form ssnn

ss = Time the train enters the macro southbound

nn = Time the train enters the rail northbound

%9   Word describing details, 3 variables abc

a is used for the lower part:

a >= 1 a lower side is drawn

a >= 2 the middle pylon is placed

b (0 – 6) describes the shape of the bridge rail, 0 means no bridge rail, you can see example 1-6 below.

c ( 0 – 9) chooses the color

%10   Range in m

Rail is visible if within range. Typical value is 7000.

The last digit is used to encode the rail texture.

%13   Timing of secondary train in form ssnn

ss = Time the train enters the macro southbound

Nn = Time the train enters the rail northbound

If %14=0 the train %7 is displayed twice per cycle

%14   Secondary train

If you try to lay a moving bridge over another rail you can only avoid the bleed-through effects in FS95 and FS98 if both rails are at exactly the same coordinates. You can read in the tutorial how to achieve this.

C) Moving bridges for FS2000 3D scenery

The representation of three dimensional objects in FS2000 is completely different to FS95/98. This allows free positioning of bridges above other rails and even several layers of bridges. Therefore a FS2000 bridge can be any standard rail without embankment but with a bridge rail and bridge pylons so that it does not collapse. The calling sequence is identical to the above list so it is not repeated here.

The following macros are available:

Length \ Width Single Dual Triple Quad
100m M1bi1100 M1bi2100 M1bi3100 M1bi4100
150m M1bi1150 M1bi2150 M1bi3150 M1bi4150
200m, 1 Slot M1bi1200 M1bi2200 M1bi3200 M1bi4200
200m, 2 Slots M2bi1200 M2bi2200 M2bi3200 M2bi4200
300m, 1 Slot M1bi1300 M1bi2300 M1bi3300 M1bi4300
300m, 2 Slot M2bi1300 M2bi2300 M2bi3300 M2bi4300
400m, 1 Slot M1bi1400 M1bi2400 M1bi3400 M1bi4400
400m, 2 Slot M2bi1400 M2bi2400 M2bi3400 M2bi4400
400m, 4 Slot M4bi1400 M4bi2400 M4bi3400 M4bi4400
500m, 2 Slot M2bi1500 M2bi2500 M2bi3500 M2bi4500
500m, 4 Slot M4bi1500 M4bi2500 M4bi3500 M4bi4500
600m, 2 Slot M2bi1600 M2bi2600 M2bi3600 M2bi4600
600m, 4 Slot M4bi1600 M4bi2600 M4bi3600 M4bi4600

The height of the rail above reference point is 1 unit = 25 cm. It is assumed that the correct level is fixed by %3.
