Preparation of Track Layout File

Each track segment in the layout must be represented by 11 lines in the data 
file.  The first line contains the name of the segment, the speed limit,
track length, etc.  The 10 next lines contain slow orders.  The filename can 
be anything reasonable but the extenstion MUST be ".DAT".  The order of the 
segments is from east to west.

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

FIELD 1. The abbreviated name of the segment prefixed with the number
	representing its position in the file.
Format: nnccccc 
Length: 7 (2 numbers, 5 characters)
FIELD 2.Speed limit for freight trains (speed limit for passenger trains is 
	assumed to be 15 miles per hour greater).
Format: integer
Length: as required (generally 2)
FIELD 3. Length of track segment in miles.
Format: integer
Length: as required
FIELD 4. Siding indicator
Format: integer  "1" if present "0" if not present
Length: 1 digit
FIELD 5. Double track indicator
Format: integer  "1" if present "0" if not present
Length: 1 digit
FIELD 6. Double track siding indicator 
Format: integer  "1" if present "0" if not present
Length: 1 digit

LINE 2. to LINE 10.

FIELD 1. Slow order speed for passenger trains.
Format: integer
Length: as required
FIELD 2. Slow order speed for freight trains.
Format: integer
Length: as required
FIELD 3. Length of track over which the slow order must be observed.
	If the slow order is for a specific point e.g. a curve, put a zero
	value in this field.
Format: real
Length: as required

EXAMPLE: Suppose track segment New York were the most easterly in the 
layout. Given a speed limit of 60, a length of 8.2 miles and a siding
but no double track, and 3 slow orders on curves, the logical record
format would be:

	01NEWYO 60 8.2 1 0 0
	20 20 0
	60 60 0
	45 45 0
	0 0 0
	0 0 0
	0 0 0
	0 0 0
