The Holden F5 Locomotive Trust

The Holden F5s operated regularly on the Epping and Ongar railway and were the locomotives used during the last days of steam operation in 1957. London Underground closed the branch in 1994 – the hope remains that it will re-open as a preserved railway in the near future. This is the motivation for the building of a replica F5.

The Eastern Counties Railway reached Loughton in 1856. The new line diverged from the Stratford – Tottenham Hale route at Loughton North Junction and close to the site of what was to become Temple Mills yard. Stations were built at Leyton, Leytonstone, Snaresbrook, South Woodford, Woodford and Buckhurst Hill. At this time the land around the line was mostly undeveloped.

The towns of Epping and Ongar were targets of further extension but construction had to wait until the ECR was absorbed into the GER. The line to Epping and Ongar was completed in 1865. The 11-mile single-track line opened on Monday 24th April 1865. The station at Loughton was re-located; the old site became sidings and was for many years used as a coal yard. Stations were built at Chigwell Road (now Debden), Theydon, Epping, North Weald, Blake Hall and Ongar.


The station building at Epping was largely unchanged in 2001

Most services ran only as far as Loughton, however Ongar was soon enjoying up to 14 daily trains to London. The Loughton – Epping section was doubled in 1892. Coal, general goods and even milk made an important contribution to traffic. Ongar station was laid out as a through station – extensions beyond Ongar, to Dunmow or back to the GER mainline at Chelmsford were contemplated but never acted upon. By the 1930s overcrowding was becoming a major problem for the services into Liverpool Street. Various solutions were considered, however, the LNER lacked the financial resources for major investment. Local rail users proposed an extension of the Central line to Eastern Avenue. The LNER proposed a straightforward overhead electrification of the line to Sheffield and the Fairlop loop. Investigation showed that both schemes would be loss making. A subsidy could not be agreed. A compromise was agreed with the Central line taking over the Fairlop loop and the line to Loughton. The future of the Loughton to Ongar section was not considered at this stage.

The compromise solution was included in the 1935 New Works Programme. Construction of the extension began in 1936. A new line in was to be built from Liverpool Street to Leyton via stations Bethnal Green, Mile End and Stratford. This was to mostly be in tunnel. At Stratford the line would rise briefly to the surface to allow cross platform interchange with local services. Another pair of short tunnels linked Stratford to the existing line just to the south of Leyton Station. A third section of tunnel would link Leytonstone with the Fairlop loop at Newbury Park. A new depot to service the increased number of trains was to open at Hainault. The work was scheduled for completion by the end of 1941.

The work was of course delayed by the outbreak of World War II. Electric train services were extended gradually reaching Stratford in 1946, Leytonstone and Woodford during 1947, Hainault and Loughton in 1948 and Epping in 1949.

Full-scale electrification to Ongar with through services to London was at one stage contemplated. However in the post-war era resources were not unlimited. In addition post-war planning had established the “greenbelt” to check the outward spread of London with future growth scheduled for the “new towns” further away from the capital. Suburban development around the eastern end of the Central Line would now be restricted.

Nevertheless a new platform at North Weald and changes to the track layout at Ongar allowed a 20-minute service frequency to be implemented in 1949. Services were now operated by a small fleet of push-pull equipped F5s (No’s 67193,67200,67202,67203 and 67213). However it was to be another 9 years (18 November 1957 – Epping – Ongar) before the electric trains reached Ongar. Initially the Ongar-Epping services were operated by the two-car 1935 stock prototype unit.

Some freight services to the many goods yards at stations along the line remained the responsibility of British Railways and were operated by J15 0-6-0 steam locomotives. Freight services were withdrawn from North Weald in 1964 and Blake Hall and Ongar in 1966.

The 1970s were a difficult era for London Transport. Cost rose rapidly whilst usage was declining. The 1969 Transport Act had transferred control of London Transport to the GLC. However the lines north of Woodford were in Essex. Essex County Council was reluctant to provide additional subsidy. Passenger levels on the Ongar section were also very light. London Transport first considered closure in 1970. Essex County council agreed to provide a subsidy provided that costs were cut. The service frequency was halved. As a result the passing loop at North Weald was no longer required and was removed in 1978.


From 1976 a single train service was introduced and the loop at North Weald was no longer required. During the 1990s ORPS members renovated the signal box seen in the background.

In the late 1970s it again seemed likely that the line would close and a preservation group was formed. Fares also increased dramatically following the “Fares Fair” confrontation between the GLC and central government. Increasing car ownership, the need to change trains and the journey times on trains designed for short journeys all discouraged traffic. However the line survived, restricted from 1981 to peak hour operation only. Blake Hall station used by literally a handful of passengers was closed in November 1981. The station building remains as a private residence though the platform was later demolished. A brief attempt was made to promote the service and an all day service was operated for a while. However, by the early 1990s usage had fallen to as low as 100 passengers per day. The service was making a loss of £184,000pa or around £7 per passenger journey. In addition it was reported that the line would need £4m of maintenance to remain in operation. London Underground applied for permission to close the line. This was granted and closure came on 30th September 1994.


From 1990 Epping-Ongar services were operated by the Cravens units. This picture was taken during the last week before closure in September 1994. It can be seen that one of the station signs has already been removed!.

However this was not the end of the story. ORPS (Ongar Railway Preservation Society) had already formed and established good relations with London Underground. Notably this had allowed restoration of the disused North Weald signal box even before the line had closed.

It therefore came as a bitter and unexpected blow in April 1996 when a new organization Pilot Developments emerged as LUL’s “preferred bidder” proposing to operate both commuter services and a heritage attraction. The motives of the new bidder came under suspicion. How could a profit making business operate a loss making railway line? Further concerns were raised by the alleged lack of railway experience of the new operators. Pilot offered ORPS the opportunity operate heritage steam trains for a fee, it proved impossible to reach an agreement. Sale of the railway to Pilot was completed in September 1998.

Pilot began to gather rolling stock at Ongar. Two four-car units of 1962 stock were propelled to Ongar by battery locos in the autumn of 1996; the 10-vehicle train was probably the longest to have ever visited the branch! However, power cables and conductor rails were removed – restoring electric traction would now be very expensive. Heavily vandalised the 1962 stock was latter scrapped. A collection of 5ft gauge steam locomotives and carriages later arrived from Finland.

Central Line services now use both platforms at Epping, this is a further obstacle to any resumption of services to Ongar

The following year Pilot pledged to have services operating by Easter 2000. A timetable was published. However though Carlton TVs series in Summer 2000 on the Underground showed a DMU in action on the line between Ongar and North Weald no public trains ever ran. The re-opening was reported as postponed; difficulties centred on access to Epping station. Central Line services now regularly use both platforms at Epping.

More recently further cars of 1962 Stock have arrived at Ongar – and then been scrapped whilst the DMU cars at Ongar have been advertised for sale. Further negotiations have failed to resolve the situation, although the EOR website states the intention of resuming services at Easter 2004. Meanwhile during 2003 other proposals for improving public transport in South – West Essex have included a wholly new railway line from Chelmsford to Stansted via Ongar or even re-opening Epping – Ongar as a guided busway have surfaced!

Cosworth expects engines to be strong

Cosworth fully expects its engines to be up to current standards of competitiveness in 2010, with the British firm confident it will return to Formula 1 in stronger shape than when it left.

The legendary engine maker will supply its V8 power units to new entrants Team US F1, Manor GP and Campos Meta next season, having last supplied F1 engines to Williams and Toro Rosso in 2006.

Speaking in an interview with’s James Allen, Cosworth CEO Tim Routsis acknowledged that the manufacturer engines currently in use on the grid had come a long way in terms of reliability in the last three years – but says Cosworth has made sure it will return with a competitive unit.


“There is no doubt that the teams have made some epically big strides over the last few years in terms of engine reliability, he said.

“The two things that really matter are that we provide a reliable and competitive engine.

“We realised that there was no future for anybody if we rocked up with an uncompetitive engine.

Routsis revealed that Cosworth has carried out tests which prove its 2010-spec V8 units will be a match for the engines currently in use by the sport’s top teams.

“We wanted to verify that what we had made sense, he said.

“So what we did was produce a complex model of the engine’s performance as it will be in 2010 and gave it to a third party agency with the largest body of data.

“We asked the question, ‘If you were to take all the results this year of the top three teams and substitute this engine into their cars, would it have affected the outcome of any of the races?’ Because that’s the ultimate measure of the competitiveness of the engine.

“The result that came back was that if the engine we are proposing for next year had been in any of the winning cars, the winning car would have still won. If it had been in any of the second place cars they would still have been second, or in one or two cases, would have won.


Although Cosworth is having to detune its three-year old engines to F1’s current 18,000rpm limit, Routsis says the fact it has free reign over the areas in which to optimise the units to the rev restrictions has given it the opportunity to make big improvements.

“It will be a lot more fuel efficient, it will obviously be retuned to the 18,000 rpm limit as opposed to the 20,000rpm limit and we are doing quite a lot of work to make sure that it is optimised to give a competitive engine, said Routsis.

“So whilst you would be able to put the two engines side by side and see a family resemblance, there is a lot of difference in the detail.

He added: “We have been given the opportunity to do a proper retune. A lot of activity that our competitors have been carrying out in the last three years has been an enormous amount of focus on areas which they were allowed to deal with, which represent small gains for enormous effort.

“We are trying to make sure that the things we focus on are the ones which give the big gains.

Since leaving F1 at the end of 2006, Routsis says the firm’s successful diversification into areas including aerospace and defence engineering consultancy allowed it to return to its 2006 turnover levels last year despite no longer being involved in motorsport – which previously made up 94% of its business.

He believes its experience in the wider engineering world means that rather than being left behind in the F1 technological game, it has learnt crucial lessons which will help it improve both its output and efficiency.

“When we diversified we thought ‘hey, hey have we got something to offer’ because we are these motorsport hotshots, but we have had to do so much learning about how smart the rest of the world is over the last few years, Routsis added.

“Actually, I think we are probably bringing back more to motorsport than we had in 2006 courtesy of some pretty hard lessons that have been given to us, particularly by the aerospace and defence boys such as how to really do things properly and efficiently.

“Motorsport has always enjoyed a huge amount of money and we thought as Cosworth that generally we would have less than everyone else and were pretty good at the way we went about it.

“Some of the lessons that we have learned from the wider world have re-set our baseline pretty harshly in terms of just how good the world outside motorsport has got in terms of engineering.

“I think sometimes in motorsport we can believe in our own publicity.”
