Preparation of Train Schedule File

Each train in the shedule must be represented in the data file by a line
containing train number, scheduled start time, etc. and then a line for each 
track segment describing scheduled stops.  The last line must contain a "*" 
character (this is required by Simscript). The filename can be anything 
reasonable but the extension must be ".DAT". The order of trains in the data 
file MUST correspond to their scheduled departures.

LINE 1. Separate each field with one or more spaces.

FIELD 1. This contains the keyword "train". It is the same for every train 
but must be present because it is required by Simscript.
Format: train
Length: 5 characters
FIELD 2. The scheduled start time of the train in 24 hour clock format.
Format: hours.minutes (no spaces)
Length: 5 (2 numbers, 1 character ("."), 2 numbers)
FIELD 3. The expected travel time including scheduled stops.
Format: hours.minutes (no spaces)
Length: 5 (2 numbers, 1 character ("."), 2 numbers)
FIELD 4. Train priority. The highest priority is 1, the lowest is 10.
Passenger trains are priority 2.
Format: n  where n is any integer number from 1 to 10.
Length: 1 digit
FIELD 5. Train number e.g. 804, 101.
Each train must have a unique number.
Format: integer.
Length: 3 digits
FIELD 6. Train length in feet.
Format: integer
Length: as required
FIELD 7. Horsepower ratio per gross ton e.g. 1.8.
Format: real
Length: as required
FIELD 8. Train's track segment origin.
Format: nnccccc       (number abbreviated name)    
Length: 7 (2 numbers, 5 characters)
FIELD 9. Train's track segment destination.
Format: nnccccc       (number abbreviated name)    
Length: 7 (2 numbers, 5 characters)

LINE 2. Separate each field with one or more spaces.  Use this line and 
succeeding lines to define scheduled stops for each track segment.
If there is no scheduled stop then enter zero values.

FIELD 1. Track segment number.
Format: integer
Length: as required
FIELD 2. Length of stop.
Format: hours.minutes (no spaces)
Length: 7 (2 numbers, 1 character ("."), 2 numbers)  OR 1 (zero)
FIELD 3. Departure time from scheduled stop.
Format: hours.minutes (no spaces)
Length: 7 (2 numbers, 1 character ("."), 2 numbers) OR 1 (zero)

LINE 3. Lines 3 to the number of track segments as per Line 2.

LAST LINE 4. Contains a "*". This is required by Simscript to identify
the end of train information for any one train.


EXAMPLE: Passenger train number 101 is scheduled to leave at 20 minutes
after midnight from New York. Its destination is Chicago and its expected
travel time is 5 hours 35 minutes. It has priority 2, a horsepower ratio 
of 2.9, and a length of 5000 feet. It has a scheduled stop of 15 minutes 
in track segment 3, leaving from there at 5:05 AM.

Freight train number 804 is scheduled to leave 7:05 in the evening from 
Chicago. Its destination is Pittsburgh and its expected travel time is 
3 hours. It has priority 5, a horsepower ratio of 1.8, and a length of 
6,200 feet.  There are no scheduled stops for this train.

For simplicity's sake assume that there are only 4 track segments from
New York to Chicago inclusive.
The train schedule data file would contain the following lines for 
these trains (in the order given).
