Toilet on the go

They appear to be almost everywhere and go by many names, few of which can be mentioned at the dinner table. Nobody really wants to talk about them, yet they are an essential part of the industrial scene used by many railroaders.
They exist due to the federal government’s Occupational Safety and Health Administration requiring companies of all stripes to provide employees with safe and sanitary toilet facilities. The portable toilet is not just an enclosed method of taking care of business away from indoor civilization. Not only is it required by various federal and state laws, but when properly installed and maintained it is safe, sanitary, and eco-friendly.
Researching this article, I found numerous companies specializing in portable toilets and was amazed at the variety and sizes that are available.
Whatever you need
There is, of course, not only the ‘regular’ portable toilet which seems to pop up almost anywhere such a facility is required, but ones equipped with sinks, flushable toilets, ADA-compliant models, and those affixed to a towable trailer for those cases where normally there would be need. An example might be new construction or a derailment where crews will have to work in the middle of nowhere for an extended period. And in some cases, you can find a solar-powered model equipped with built-in lighting, and multiple toilet models ready for big crowds.
Really fancy ones can be brought in for bigwigs and celebrities. Upper-end frills can include incandescent lighting, heat, tiled floors, mirrors, fans, and music!
They are a science all their own
Portable toilets are not connected to local water systems and usually carry onboard chemicals that hold and break down the waste in holding bins. Usually, they are scented, sometimes not.
While they look hastily put together, they are carefully designed not to leak, provide ventilation, and most importantly be as sanitary as possible.
As a footnote, yes there is an established process to take care of them when their holding tanks are full. The portable toilets can be drained on-site or easily replaced by a fresh one.
This proves once and for all that one person’s waste can be another person’s career.
