what is it?

The British Rail Class 144 Pacer is a retired class of diesel multiple unit (DMU) passenger trains built at Derby between 1986 and 1987. British Rail, seeking to procure improved derivatives of the earlier Class 141, placed an order with the manufacturers British Rail Engineering Limited (BREL) and Walter Alexander to construct their own variant, the Class 144. A total of 23 units were constructed.
