Photos:

Here you can see an LGB 1705 track magnet 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..
