Looking in my Tillig Gleis-Katalog (worth owning) the article number for Tilligs TT-Advanced track system function tracks (Funktionsgleise) isBruno Strasser wrote:The pins won't fit in to the tillig track. I think it is a solder job or I might drop tillig a note to look for the dcc track with no capacitor ...
83149 - 166mm Straight railway siding (for digital handling)
Tillig also contact clips that hooks to the rail and has a solder eyelet, comes in a bag of 20 pieces, article number 85506. You could do a search with that number to see what they look like.
And last but not least Tillig has a 2 pole connection cable with a plug for functional tracks (length 890 mm, cable diameter 0.15 mm square) article number 08913
You could skip the above cable, I did an internet search for that function track and the picture also show a plug in cable
