DRAW

DRAW (sp) index (sp) layer (sp) lineType (sp) 0 (sp) 0 (sp) start-x (sp) start-y (sp) start angle
    A set of line segments
    END$SEGS

Note that most often the start-x and start-y is set to the layout origin 0,0, but it doesn't have to be. The start-angle is a rotation about that origin - most frequently 0.

LineType - 0=solid, 1=dashed, 2=dots, 3=dash-dot, 4=dash-dot-dot

JOINT

JOINT (sp) index (sp) layer (sp) width (sp) 0 (sp) 0 (sp) scale (sp) visible&no_ties&bridge&roadbed (sp) L0
(sp) L1 (sp) R (sp) L (sp) flip (sp) negate (sp) Scurve (sp) x (sp) y (sp) 0 (sp) angle
    Two end points (Both Ts as a JOINT must be connected)
    END$SEGS

The Joint is used for joins that don't use a Cornu. The values of L0, L1, R and L are taken from the settings of the Join screen - they define the shape as a part cut using L0 to L1 of a standard curve with offset from an arc of radius R of Length L. Negate means the curve is reversed. Scurve is two identical transition curves joined back to back each of half the gap length. x and y is the relative origin and angle is a rotation angle.

TURNOUT

TURNOUT (sp) index (sp) layer (sp) options (sp) postion (sp) 0 (sp) scale (sp)visible&no_ties&bridge&roadbed (sp)origx (sp) origy (sp) elev (sp) angle (sp) "Manufacturer<tab>Description <tab>Part<tab>"</tab></tab></tab>
    A set of X records for Adjustable or Piers or Curved Ends - optional
    A D Description record
    A set of P Path records
    A set of track segments (one or more)
    A set of line segments (if any)
    END$SEGS

A turnout is a group of segments that are treated as a unit - A turnout always has at least one track element and may not actually be a turnout in railway terms at all (could be a simple fixed piece of track). It is defined so that all the segments within are relative to its origin and angle. The same definition (with zero origin and 90 degree angle) exists in the parm file. The scale is used to decide whether to show it in the hotbar. Note that the definitions up to and including V5 all have the track elements first and any line segments second. This means the line segments will be drawn on top of the track.

Options is a set of values that are added together.

Turnout/Structure Options

Options	Meaning
0-7	Width
8	Handlaid
16	Flipped
32	Ungrouped
64	Split
128	Label Hidden
256	Override
512	NoCombine

Handlaid indicates the TURNOUT is HandLaid.

Flipped, Ungrouped and Split specify that the object has had one or more of these operations applied.
Label Hidden controls whether the label is hidden.

Override and NoCombine control how paths are created for TURNOUTs. Override means that no automatic path generation is done. NoCombine means that Sub-Path Combination is not done, typically for Turntables, Transfer Tables and Double Slip switches. This is for future work, but these flags are ignored for now.

STRUCTURE

    A D Description record
    A set of line segments
    END$SEGS

A structure is a group of segments that are treated as a unit - A structure has no track elements. It is defined so that all the segments within have positions and angles are relative to its origin and angle. The same definition (with zero origin and 90 degree angle) exists in the parm file. The scale is used to decide whether to show it in the hotbar.

LineType - 0=solid, 1=dashed, 2=dots, 3=dash-dot, 4=dash-dot-dot

Options is a set of values that are added together. Note -> not all of these may apply to a structure. See Turnout/Structure Options above.

Title consists of a set of tab delimited fields that are arranged like this Manufacturer<\t>Prototype<\t>Description<\t>Part<\t>Road<\t>Reporting Mark<\t>Number

The truck-center offset is the offset in inches increased by 1000 to turn it into an integer.

If deployed on the layout, a line of details is appended to the object definition line
