Here you can see an LGB 1705 track magnet (no longer available) mounted between railroad ties on LGB track. This magnet does not work well on non LGB track and is not flexible in placement as only some ties are wide enough to allow installation. The LGB 1705 uses a very small low cost magnet that must be elevated close to the locos reed switches as it has a week magnetic field. If you open up the housing you will notice the magnet placement under the elevated black raised rectangle shown below. This high placement causes many locos to hit the surface of the magnet causing wear by grinding off the LGB logo on the right side of the housing. Eventually this will expose the magnet and ruin the device and locos..

Here you can see the lower profile of the Shourt LIne SL-TM-1705 does not interfere with your locos undercarriage. The use of a Neodymium magnet allows a much smaller, more prototypical, housing. SL-TM-1705 mounted on LGB track

For invisible installation of a track magnets use the Shourt LIne SL-TMU-1705 track magnet shown below. This is a good choice when you want invisible placement of track magnets inside your railroad ties. Here you can see the placement between one rail and the center mounting hole of an LGB 1000 style track. These use the maximum available magnet size while still fitting perfectly inside a LGB railroad tie. SL-TMU-1705 invisible track magnet

The Shourt Line SL-TM-1705 provides the ultimate in flexibility and ease of installation with all Manufactures track, locomotives and rolling stock.

For indoor or outdoor use.
