Rails are too light and 'eccentric' (off-center) mounted on / attahced tor unning rail to carry the weight of a full-size freight car and the loco that wold be pushing / pulling it. 

There are limited trials of "jump frogs" - a/k/a "flange-bearing frogs" - and similar switch points (can't remember the precise term for them this late at night) that can handle full-size equipment, but nothing widespread.

This is one way to get to a temporary or unused siding without cutting the rail.  Any idea how slow a tain car switch woud be ?  Says it is for track machinery but have seen cars on such a siding. http://www.martinusrail.com.au/products-and-services-app/temporary-portable-turnout-l4  

5-10MPH switch - these things have been around for 50+ years. Limited application. Except for larger machines like tampers/liners/regulators/switch grinders,  mobile cranes are more effective use of time and money. Running revenue cars over a temporary TO raises eyebrows at FRA.
