The Orenstein & Koppel well tank was available in a range of standard designs and primarily marketed as a ‘contractors’ type locomotive, supplied to small industrial firms for internal networks or construction projects. In the UK they were used for both and there are a number of examples preserved, including Penrhyn’s "Eigiau" now based on the Bredgar and Wormshill in Kent. Our model depicts a typical example and is based upon prototype drawings. Larger tanks, as depicted, were available as an option on the prototype.
