Attaching Track to Lionel Trestle

[Anonymous]

If you are talking about the trestle sets, numbers 110 and 111, for traditional Lionel tubular track, I believe the answer is #4 x 1/2 inch,  sheet metal screws in black. The part number is 110-25.

Per Complete Service Manual for Lionel Trains by K-line, 1982 edition, page 412

What size screws do you use to attach tie channels from track to rails?
