<p>The <b>Class 4000</b> is a type of <a href="Diesel_multiple_unit" title="Diesel multiple unit">diesel multiple unit</a> (DMU) in service with <a href="NI_Railways" title="NI Railways">Northern Ireland Railways</a>.

</p><p>The fleet was procured due to the recognition of the essential role railways play in economic growth and the need to replace outdated rolling stock, particularly <a href="NIR_80_Class" title="NIR 80 Class">Class 80</a> and <a href="NIR_450_Class" title="NIR 450 Class">Class 450</a> trains. After receiving funding from the <a href="Northern_Ireland_Assembly" title="Northern Ireland Assembly">Northern Ireland Assembly</a> and issuing a tender, NI Railways awarded the contract to <a href="Construcciones_y_Auxiliar_de_Ferrocarriles" title="Construcciones y Auxiliar de Ferrocarriles">CAF</a>, which already had a successful track record with the <a href="NIR_Class_3000" title="NIR Class 3000">Class 3000</a> units. The Class 4000 trains entered service in 2011, with significant internal differences from the C3K fleet, such as increased seating capacity and improved fuel economy. The trains have replaced the remaining Class 80 and Class 450 trains, increasing capacity and allowing longer trains to operate. In 2018, 21 additional vehicles were ordered to further extend train lengths. Despite some reported technical issues, testing for six-car formations started in 2021.

</p>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>The fleet covers 20 DMUs procured by <a href="NI_Railways" title="NI Railways">NI Railways</a>. None of the Northern Irish rail network is electrified, and diesel multiple units have been used since nationalisation in the 1950s.

</p><p>Prior to 2000, the NIR rolling stock consisted of a mixture of <a href="Diesel_multiple_unit" title="Diesel multiple unit">diesel multiple unit</a> types that had entered service between 15 and 25 years previously. The main type was the <a href="NIR_Class_80" class="mw-redirect" title="NIR Class 80">Class 80</a>, based on the <a href="British_Rail_Mark_2" title="British Rail Mark 2">Mark 2b</a> bodyshell, 22 3-car and 4-car units built in two batches between 1973 and 1979. Additional capacity was provided with the <a href="NIR_Class_450" class="mw-redirect" title="NIR Class 450">Class 450</a>, nine 3-car units that entered service in 1985 based on the <a href="British_Rail_Mark_3" title="British Rail Mark 3">Mark 3</a> bodyshell. Chronic underinvestment in the railway meant that by the millennium these were the newest domestic trains. By 2000 it was estimated that the network required investment of £183 million to bring it up to basic safety standards.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading3"><h3 id="New_trains">New trains</h3></div>

<p>Recognising that the railways serve an important role in the growth of the local economy, the devolved <a href="Northern_Ireland_Assembly" title="Northern Ireland Assembly">Northern Ireland Assembly</a> granted funding for improvements in December 2000 following the report of the Railways Task Force.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Included was £80 million for rolling stock, the largest order in the history of NIR. The result was the <a href="NIR_Class_3000" title="NIR Class 3000">Class 3000</a> DMU from <a href="Construcciones_y_Auxiliar_de_Ferrocarriles" title="Construcciones y Auxiliar de Ferrocarriles">CAF</a> in Spain, 23 three-car units used to replace the increasingly outdated Class 80. They entered service between 2004 and 2005. This was a like-for-like replacement meaning that older rolling stock had to be retained, and NIR could not introduce the service enhancements it desired.

</p>

<div class="mw-heading mw-heading3"><h3 id=""New_Trains_Two"">"New Trains Two"</h3></div>

<p>The expanding economy led to increasing pressure to improve the rail network, with recommendations made in a debate in the Northern Ireland Assembly in May 2007.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> Among these was the purchase of rolling stock to replace the remaining Class 80 and Class 450 trains. Translink instituted the "New Trains 2010" (later renamed "New Trains Two") proposal for new trains,<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> and decided that it needed to improve its service frequency to go with the associated infrastructure improvements, which would mean expanding the fleet. The proposal was that up to 20 trains would be purchased, which would replace the Class 450 and 80 units and expand the fleet by up to seven trains. The go-ahead was given on the publication of the draft budget of the <a href="Department_for_Regional_Development" class="mw-redirect" title="Department for Regional Development">Department for Regional Development</a>, which allocated £137 million over three years to Translink, including for 20 trains.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>

</p><p>Translink issued the <a href="Invitation_to_tender" title="Invitation to tender">invitation to tender</a> (ITT) in June 2008. Three firm offers were received: <a href="Bombardier_Transportation" title="Bombardier Transportation">Bombardier Transportation</a> offered the <a href="British_Rail_Class_172" title="British Rail Class 172">Class 172 <i>Turbostar</i></a> being built for operation on the <a href="Rail_transport_in_Great_Britain" title="Rail transport in Great Britain">British network</a>; <a href="Hyundai_Rotem" title="Hyundai Rotem">Hyundai Rotem</a> a variant of the <a href="IE_22000_Class" class="mw-redirect" title="IE 22000 Class">22000 Class <i>ICR</i></a> purchased by <a href="Iarnr%C3%B3d_%C3%89ireann" title="Iarnród Éireann">Iarnród Éireann</a> (ruled out because of NIR's desire to have units with <style data-mw-deduplicate="TemplateStyles:r1154941027">
