With the advent of spring, garden railroaders need to carefully check their layouts for a potential buildup of dihydrogen monoxide (DHMO), also known as hydroxyl acid. DHMO is a by-product from the burning of fossil fuels and is the major component of acid rain. It accumulates naturally on brass, aluminum, and stainless steel rails over the winter months.
The National Oceanic and Atmospheric Administration (NOAA) reported record levels of DHMO this past winter, especially in the northeastern portion of the US.
DHMO can cause electrical failures in your locomotives and significantly decrease traction. It also contributes to the erosion of ballast and can adversely affect the appearance of structures.
Use caution when removing DHMO from your layout. It can cause severe burns and accelerates the corrosion of many metals. It can be fatal if inhaled.
