The British Rail Class 230 or D-train is a diesel electric multiple unit being built by Vivarail for the British rail network. The units are being converted from London Underground D78 Stock, first built in 1980 by Metro-Cammell.

It is proposed to run 75 units of two or three cars per unit.[1][2] They will become known as Class 230 under TOPS.[3] A prototype was produced for testing and accreditation in August 2015, and the type is planned to enter passenger service in 2016.[4] They are to be tested in mainline service on the Great Western Railway network.[5]

D78 Stock conversion

London Underground D78 Stock, which Vivarail plans to refurbish

In November 2014, Vivarail bid for, and successfully bought, 150 driving motor cars and 300 carriages of ex-District Line D78 Stock from London Underground, which were being replaced by S Stock ahead of their lifespan, so that the subsurface lines (Circle, District, Hammersmith & City and Metropolitan) could have a common rolling stock fleet compatible with a new ATO system. The stated purpose of the D-train is to ameliorate a perceived shortage of affordable, modern rolling stock on Britain's regional rail routes, resulting from the slow pace of electrification.[6]

Overview

In the conversion programme, the company plans to re-use the aluminium bodyshells, traction motors and bogies from the D78 units, and fit them out with new diesel engines and interiors. Rail Magazine reports that each power car will have two underfloor engine-generator sets. The 3.2 litre, five cylinder diesel engines will be made by Ford in South Africa. Vivarail claims that fuel consumption will be around 0.5 litre per car per mile. This is about half the fuel consumption of a Pacer. Maximum speed will be 60 mph (97 km/h).[7]

The first D78 units were delivered to Vivarail on 19 January 2015. A single car prototype was produced and ran on Vivarail's 2.5-mile (4.0 km) test track in summer 2015, with a full length prototype to run on the Great Western Railway network in the autumn.[8][9]

Marketing

Vivarail have stated that they plan to pitch the converted trains to a number of train operating companies (TOCs), especially those bidding for the Northern Rail franchise coming up for tender on 1 April 2016.[8] They are positioning them as a cost-effective alternative to buying brand new rolling stock, enabling TOCs to replace the "Pacer" railbuses in the North of England with upcycled Tube stock. However, the wording of the Invitation for Tender for the next Northern franchise released on 27 February 2015 seemed to suggest converted D78s cannot be used, as it stated only the following types of self-powered trains could be used by Northern post-December 2019:

"Pacer" railbuses in the North of England, Wales and South West England that Vivarail D-trains are intended to replace or supplement.

Arriva won the bidding for the Northern franchise in December 2015 and their rolling stock plan involves an order of brand new Diesel Multiple Units, an order of brand new Electric Multiple Units, plus cascades of Diesel Multiple Units released by GWR and Scotrail,[11] as well as taking on additional cascaded 4 car EMUs.[12] According to BBC Look East, Vivarail are currently in talks with bidders for the next East Anglia rail franchise which Abellio, First Group and National Express are currently preparing bids for.[13] The East Anglia franchise includes some very rural routes where currently only single carriage trains are used.

Advantages and disadvantages

The proposal has been criticised by the Rail Maritime and Transport Union (RMT) as a scheme to provide "second-hand" trains to the region instead of new stock.[14] Nevertheless, their low cost allows for more to be ordered and they were built and will be upgraded in Britain, unlike most new stock. They are also built of aluminium, making them immune from corrosion, and, having undergone recent major refurbishment, are in good condition and have relatively new bogies. The D-Train meets all current standards up to and including the 2020 PRM-TSI regulations, which the Pacer railbuses do not. The trains are more environmentally friendly, due to stop-start diesel engine technology, light-weight build and up-cycling of the majority of the cars. The upgrading will also take a much shorter time than would be the case of planning and building trains from scratch, as well as being roughly a third of the price.

Potential customers

In May 2015, it was claimed Arriva Trains Wales were to open talks with Vivarail over taking on converted D78s.[15] Under a recent franchise agreement, FirstGroup (owner of the Great Western Railway franchise) has agreed to carry out a study on the use of overhauled Vivarail D-Trains on branch lines by the end of the year, possibly leading to a trial of the units.[16]

In September 2015 it was revealed that Coventry City Council were looking into the possibility of using converted D78s to run extra services on the Coventry to Nuneaton Line; this would be especially useful to serve Coventry Arena station during match days at the Ricoh Arena, to alleviate a shortage of rolling stock.[17]

In 2016, Marshlink Trains, a pressure group seeking to improve the service level on the Marshlink Line, set up a petition advocating the procurement of Class 230 units to operate a shuttle service between Ashford International and Rye in peak time, allowing Class 171 units to be transferred to strengthen peak time Ashford International to Brighton services.[18]

Confirmed Orders

Great Western Railway have confirmed that they will run trial runs on the Plymouth to Gunnislake service.[citation needed]
