A Garratt (also known as Beyer-Garratt) is a type of powerful Steam locomotive that is articulated in three parts. Its boiler is mounted on the centre frame, and two steam engines are mounted on separate frames, one on each end of the boiler.
Articulation permits larger locomotives to negotiate curves and lighter rails that might restrict large rigid-framed locomotives. Many Garratt designs aimed to double the power of the largest conventional locomotives operating on their railways, thus reducing the need for multiple locomotives and crews.
This exhibit had problems like corrosion, flaking of paint layer, rusting, missing/broken parts.
The parts of locomotive like under-frame, boiler, steam dome, chimney and areas of the tender were badly corroded.
