The Plasser and Theurer 09 series supplement earlier tampers (which tamp or pack down the ballast under sleepers to maintain a firm track bed), including the company's
08 Series also used by Network Rail. The
09-3X tampers, known by Plasser and Theurer as
Tamping Express, have been built since 1996 and over three hundred have been delivered worldwide [1]. They operate on three sleepers at a time and offer higher performance than earlier types. The tamper also has an Automatic Guiding Computer and each sleeper bank can be lifted or lowered individually to cope with track of lower quality.
