[4] The D&KR engaged John Urpeth Rastrick as consultant to visit the prospective builders and he returned with a specification which matched an improved Experiment locomotive from Sharp Brothers of Manchester.

They would have originally preferred to have placed all six with one manufacturer for parts commonality however ability to complete the build in the needed timescale had become a priority and degrees of uncertainty about both designs may have been a factor.

[d] The labourer was later to die of his injuries and the "occasional engineman" charge of Swiftsure was held responsible for entering a watering stop at more than 6 miles per hour (9.7 km/h) and was sanctioned by losing his turn on the promotion list.

The L&MR was ultimately advised to pay £3,000 damages for the high value load on the basis they had not adequately displayed notices that the owners should have insured it.

[20] The Forresters' locomotives for the D&KR became known as Vauxhall, Dublin and Kingstown; the names being those of the manufacturing foundry and the termini of the line.

The first of the D&KR locomotives[e] ran sufficiently well on tests on the L&MR that it was permitted by their superintendent Manchester to take charge of the first class train to Liverpool on 27 June 1834.

The journey was completed in 1 hour 17 minutes with several D&KR people on board including James Pim, Thomas Flemming Bergin, Vignoles and other directors.

[21] The first recorded service of the invited members of the public being transported was a special preview trip to Martello Tower and Booterstown by Vauxhall on 4 October 1834.

The honour of the first trial run over the entire length of the line fell to Forresters Hibernia on 9 October 1834 with Vauxhall doing a trip later in the day.

[citation needed] The honour of the first scheduled train in Ireland fell to Sharp's locomotive Hibernia at 09:00 17 December 1834; this being the famously celebrated inaugural run.

Maintenance of the class was at the Serpentine Road "engine hospital" with one section reserved for Forrester locomotives with their man Alexander Allan on site for one year per the purchase contract.

[22] On 28 March 1835 the motive power situation became desperate when Forrester locomotive's Vauxhall and Dublin were in collision, with requests to England for spare tenders.

[22] The order for two 2-2-0T locomotives's was put in Forrester's, in the event these were named Comet and Victoria, with Murray claiming these were "the first tank engines to work on any public railway".

[24] The London and Greenwich Railway began a public service on the 2+1⁄2 miles (4.0 km) section between Spa Road and Deptford in February 1836.

[citation needed] Victoria had a trailing axle added in 1841 to become a 2-2-0, before becoming a pumping engine at Bricklayers Arms from December 1845 and was finally acquired by C. Tomkins at Reading for scrap for £110.

[31] With their 2-2-2 wheel arrangement they were totally unsuited and never intended for climbing the steep Lickey Incline and for this ascent they were assisted by the Norris Type A Extra bank engines.

[32] The Preston and Wyre Railway (P&WR) had a Forrester 2-2-0 it sued for light goods, ballasting work, and occasional special passenger trains.
