Hoy, esperando a pasar un paso a nivel, he visto un defender circulando por la via ferrea  😮 con dos ejes de vagoneta en la parte del. y tras. y sus 4 neumaticos de goma girando tambien. Ojalá lo hubiera podido fotografiar  >:( Incluso " pitaba " igual que el mismisimo TALGO  ;D

Rail Rovers

The rail conversion was tried on a number of occasions.
One of the first "Rail Rovers" used flanged railway wheels in-place of the road wheels.
This was intended for inspection and light shunting.
Trials showed that shunting was impractical due to the size of the rolling stock compared to the Land Rover.
The flanged wheels later had a rubber composite 'tyre' for better traction, but the project never really gained interest from the projected customer base, and was quietly dropped.

More successful, were the combined road/rail conversions.
These vehicles demonstrated quick acceleration when compared to small conventional locomotives.
Intended to move personnel and small equipment, the main problem was that the Land Rover was often too small to trip the train detection circuitry, hence these kinds of conversions saw limited use in the UK.
Permaquip built some Road/Rail Land Rover Defenders.
Using the "Hy-Rail" conversion, the vehicles can be quickly made to run on railway tracks.
They can tow two loaded trailers and travel at 15mph on the rails.
The vehicles carry standard British Rail safety devices including front and rear lighting and an air horn.
