What are some good railroad ties for landscaping steps?

Some good railroad ties for landscaping steps are ties that are strong, termite- and ant-free, level and resistant to rot. Desirable ties also include old ties without much creosote.

Good railroad ties for landscaping steps include level ties resistant to bending from weathering in the elements. Ties infested with ants or termites are prone to weakness and facilitate the spread of pests and therefore are not suitable for use. Creosote staining, which gives ties a black or dark color, helps promote rot resistance but also leaches into the soil. Good landscaping ties include older ties with less creosote, as evidenced by a relatively pale color.
