Working on a building project for a rail car company, and they are talking about using "snap track" on the slab for the cars. What is "snap track"? Is this the same as "Panel track" (pre-fab rail road track panels), +/-80 ft long?
My understanding is that prefabricated trackage is mostly referred to as panel track, prefabricated sections of railroad track and/or switches. Somebody may be confusing it with model railroading where there is an Atlas snap track. Panel track is sometimes nicknamed "snap track" after the model railroad name for pre-assembled sections of track which are easily snapped together.
On rail wreckers are pretty obsolete now, the vast majority of derailments are handled by off rail contractors with caterpillar sidebooms and cranes. It is more convenient to use trucks to transport the panels.
Panels are used in derailment restoration, grade crossing renewal, ballasted deck bridge construction, new construction and accident restoration (washout's, slides, etc.)
