Tie Down TranzVolt G2 4 ft Base Track Section with Warnings
The 40659 is the 4 ft base section that anchors every TranzVolt G2 track run. It carries the bottom shoes, the bottom stop bracket mounting points and the warning labels, and it pins to the 8 ft sections (10091) above it.
Order it as a replacement for a damaged base, or as a spare so a rental fleet or a second crew can build a second track run from shared 8 ft sections.
