The British Rail Class 321 alternating current (AC) electric multiple units (EMU) were built by BREL York in three batches from 1988 to 1991. The design was successful and led to the development of the similar Class 320 and Class 322 units for use by Strathclyde PTE and Stansted Express (now used by Northern Rail) respectively. The British Rail Mark 3 bodyshell design was also used for construction of the Class 456 direct current (DC) units.
Three sub-classes of unit were built. The first two were built for the Network SouthEast sector, whilst the final batch was built for services around Leeds. These trains have been modified by different rail companies who use them such as Greater Anglia. The modifications include new seats, paintwork, lighting and in carriage announcement boards.
The first batch of 66 EMU trains, built between 1988 an 1990 were classified under TOPS as Class 321/3. Units were numbered in the range 321301-366 and have a maximum speed of 100 mph (161 km/h). Each EMU consisted of four carriages; two outer driving trailers, one of which contained first class seating; an intermediate motor coach with standard class seating only, roof mounted Brecknell Willis High Speed pantograph and four Brush TM2141C traction motors (two per bogie); and an intermediate trailer with standard class seating. The technical description of the formation is DTCO+PMSO+TSO+DTSO. These units were delivered in two groups, with individual vehicles numbered as follows:
Units 321301-346 Units 321347-366
DTCO 78049-78094 78131-78150
PMSO 62975-63020 63105-63124
TSO 71880-71925 71991-72010
DTSO 77853-77898 78280-78299
These EMU trains were built for outer-suburban trains on the Great Eastern Main Line, primarily from London Liverpool Street to Southend Victoria, Ipswich, Southminster, Clacton, Colchester and Braintree. They replaced the ageing slam-door Class 305, Class 308 and Class 309 units on trains to Clacton and Southend-on-Sea, and worked services on the newly electrified routes to Ipswich and Harwich. They also displaced many Class 312 slam-door units to the London, Tilbury and Southend Railway. Some of the Class 309 “Clacton Express” units were retained until 1994, and 24 of the newer Class 312 units were retained long-term to work services to Walton-on-the-Naze and peak services to Clacton, Ipswich and Witham. Units carried the distinctive Network SouthEast livery from new. 321361 was named ‘Phoenix’ in March 2008 at Ilford depot after it was rebuilt at the disused Colchester shed to repair damage caused by an arson attack at Southend Victoria on 10 July 2007.
The EMD F59PHI is a quasi-high speed locomotive produced by Electro-Motive Division (EMD) from 1994 to 2001. It features an isolated cab, lightweight body, and a streamlined shape, features that were absent on the original commuter F59PH.
First built for the California Department of Transportation, the F59PHI has seen service in all four corners of America, as well as in the Pacific Northwest/Montreal area in Canada.
In 1990, the State of California passed a bill that would result in massive funding for the state transportation systems. It also resulted in a separate, state funded system of regional Amtrak routes.
CDoT wanted a locomotive that was both reliable and attractive. They approached EMD, who responded with the lightweight, high-speed F59PHI locomotive.
Soon after, more orders arrived. Amtrak ordered 21 of these locomotives for their Pacific Sufliner service (separate from Amtrak California), and the North Carolina Department of Transportation also selected it as their primary motive power. West Coast Express (operated by TransLink) in Metro Vancouver, also selected it for starting up its service.
Montreal’s Agence de Metropolitaine de Transport bought 11 of these locomoties to go with their Bombardier BiLevel coaches, which were just arriving.
The F59PHI was produced until 2001. It was taken off of EMD’s lineup because it wasn’t able to meet the EPA Tier 1 regulations.
Some of Amtrak California’s F59PHI’s have been rebuilt by EMD, these are ECO repowers.
Sound Transit’s 2015 budget outlines plans to overhaul seven F59’s and four of those will be overhauled to Tier 3 standards. (Most likely by EMD as ECO repowers).
