The Tillig Bedding track is inspired by Kato Unitrack but is not made by Kato. Tillig buys UniJoiners in bulk from Kato and manufacturers their own track.
As the Tillig Road bed track has a few quirks this page will talk about the track components and how they go together.

Track pieces

Track Pieces
Straight Track
83701 BG 1 166.0 mm Straight Track
The BG 1 track piece is the standard straight track. Three BG 1 less 1mm is the length of a standard straight module - 497mm or ~ 19 9/16"
83702 BG 2 83.0 mm Straight Track (1/2)
One half of a BG 1 straight track piece.
. I have been using a BG2 cut in half on the joining edges of modules that use flex track for the main lines. Remove the track from the BG2 before cutting it in half. After the BG2 half pieces have been glued down, run the flex track rail to the module edge.
83703 BG 4 41.5 mm Straight Track (1/4)
One quarter of a BG 1 straight track piece.
83704 BG 5 36.5 mm Straight Track
BG 5 (and BG 3) are used to correct the geometry problems caused by a crossover.
83705 BG 3 43.0 mm Straight Track
BG 3 (and BG 5) are used to correct the geometry problems caused by a crossover.

83740BG 1 Straight Road Bed Track (166.0 mm) with Filter Capacitor
! One of these comes with each train set.
Before using one of these on a DCC equipped display, remove the filter capacitor. It will short out the DCC signal if you are using DCC.
There is no reason to purchase one of these separately.
Curved Track
83706BR 21 353mm/30 Degree Curved Track (13.9" Radius)
83707BR 22 353mm/15 Degree Curved Track
BR 2x is the outside curve on the small corner modules.
83709BR 11 310mm/30 Degree Curved Track (12.2" Radius)
83710BR 12 310mm/15 Degree Curved Track
BR 1x is the inside radius used on the small corner modules.. This sharp curve does not lend itself well to longer North American equiment.
There is no BR 3x curved piece but if it existed it would be 396mm. This could be made with flex track or using standard track pieces #83111 - R 31 - Curved track: R 15 5/8" / 30 on a roadbed. Used on Medium corners as the outer main.
There is no BR 4x curved piece but if it existed it would be 439mm. (17.28" Radius). This can be made with flex track. Used on large corners as the inner main.
There is no BR 5x curved piece but if it existed it would be 482mm. (19" Radius). This can be made with flex track. Used on Large corners as the outer main.
There is no BR 6x curved piece but if it existed it would be 525mm. (20.6" Radius). This can be made with flex track. Used on the station corner as the outside passing track.
Additional concentric curves would be:
  • BR 7x - 568mm - ~ 22.3"
  • BR 8x - 605mm - ~ 23.8"
  • BR 9x - 648mm - ~ 25.5
  • BR 10x - 691mm - ~ 27.2"
  • BR 11x - 734mm - ~ 28.9"
  • BR 12x - 777mm - ~ 30.6"
These would all be made from flex track.

Turnouts
83816Manual Right Hand Turnout
Standard 15degree angle turnout, equivalent radius R22 (353mm)

83817Manual Left Hand Turnout
83818Remote Right Hand Turnout
83819Remote Left Hand Turnout
The 15 degree turnouts are equivalent to a #3.9. Much too sharp for anything but short equipment. Longer equipment will work at slower speeds but does not look too good.
83861Right Hand Curved Turnout
Curved right hand turnout: radiuses BR11 (310mm) and 631mm /15 degree (about a BR18.5).

83862Left Hand Curved Turnout
The Tillig 15 degree turnouts 83816-83819 and 83861 and 83862, are deprecated now that Kuehn has released a good #6 turnout. They should be removed from Mainline use and limited to slow speed industrial areas.
