The construction kit contains a compressor house with attachments and accessories, a stationary pipe-blasting frame and a coal rake rack with the respective hand apparatus for cleaning and removing slag from the steam engine. Every depot facility has a compressor house for the supply of the compressed-air ductwork system. The engine repair shed, the sanding tower and the pipe-blasting frame among others are fed with compressed air from here. From time to time the flues and fireboxes of the locomotive have to be thoroughly cleaned by blasting with the tubular extension pole.
