We recommend this solder for building trackwork in the Fast Tracks assembly fixture Builders' Guides and videos. This is a rosin core, 60/40 (60% tin, 40% lead), 0.020" diameter solder. The small diameter of the solder makes it ideal for soldering trackwork.

This solder is sold in 15' lengths. Enough to construct several dozen turnouts.

    Very satisfied as this solder is ideal for soldering turnouts

    This is a good size of solder for the turnouts for my Z scale layout. No big blobs of solder on the ties! On a segue, I also used this when making up my 25 pin sub-D connectors for my frog juicer and DCC turnout decoder boards. Smaller diameter easily fits into solder connections.

    Nice size wire if you are soldering small gauge wire ,especially if your doing any decoder work if soldering is required.

    I like the solder, but it tends to get knotted up sometimes in the container. Frustrating.

    Much easier to use than the larger diameter solder I had been using. Hard to believe a rosin core solder could be .020" dia. But now that I have it, I will keep using it.

    This solder is perfect for PCB tie track construction. The key to PCB to rail joints is neat solder work, and the best work I've done so far is with this solder. I can precisely apply solder exactly where I want it withe the small diameter wire. No excessive solder blobs, very clean connections, and less work cleaning up afterward. Price is very reasonable, too.

    Very fine and thin solder. As mentioned in Another Review; it can get stuck in the small container which is a bit annoying but easely solved but cracking the lid of the container and untying the nut....

    Small and thin and easy melting. Ideal to solder small parts.

    The solder is as advertised - thin in diameter- and arrived promptly.

    Absolutely the best solder I have found for building turnouts and track!

    Great small diameter solder for track work. As noted by another reviewer in can get knotted as you pull it out of the container.

    Just the good diameter for the track work soldering. Very satisfied with it. Can get blocked in the container but it’s easy to correct.

    When they say small diameter they Mean small diameter. The solder bends much too easy and requires constant re-curving to get it in the right spot. This is dangerous when dealing with a hot soldering iron. I wound up twisting two pieces together to get it to keep its shape. Otherwise it definitely solders quite well.

    Love this solder. The small diameter is excellent for soldering rail.

    Just the right size to use on making switches as to not put to muc solder in one spot.

    I purchased this solder to connect jumper wires on track. It works great and is much better than large diameter solder for fine details.

    An excellent solder in a hard to find small diameter.

    I like the solder; works very well on the turnouts - but it tends to get knotted up in the container.

    I have recently built 100 feet of main line and branch line. I tried other solder, but found Fast Track's solder superior. The size (width) of the strands allows just the right amount of solder to make a clean connection. One doesn't want a big glob of solder along the inside tracks as it'll prevent proper train flow. All you need to do is break off a tiny drop of solder and run along the PC ties to make a fantastic joint. Love this stuff. Wouldn't do track or turnouts with out this!

    Great product. I use it also for other modelling work as well. I do get frustrated when it jams up in container because when it is coming out right it’s makes using it so great.

    Solder diameter matters! I began using electronics solder that I had and it was okay, but I had to be very, very careful not to apply too much. With this very fine rosin-core solder, it is much easier to get the correct amount of solder into the rail-PC tie connection, creating a very neat and well-functioning turnout!
