The first post looked at primarily Ipswich buffers under test in Argentina. This post looks at a few more of those – but its mainly the more modern types such as Oleo buffers that are being tested.
There are still a number of stations and sidings with Ipswich buffers. The only large terminus in England (apart from London) to still have any substantial number of Ipswichs these is the disused Mayfield station in Manchester. These might not be long for this world however if development plans go ahead.
Bradford Interchange has some which are preserved as part of the station’s heritage. These were originally at Bradford Exchange. Crewe still has some in the bay platforms used for Chester/North Wales services.
The underground has a few examples still remaining – both Ipswich and other unknown manufacturers (a mix of modern and old types). In terms of London termini Waterloo has the biggest collection of Ipswich buffers. Paddington still has a couple despite the other platforms now having friction style buffers. I thought these remaining Ipswich examples at Paddington were being removed but someone there advised me they aren’t.
A major Scottish terminus with a good selection of Ipswich buffers and these are kept in top condition as the following videos show.
The buffers here are of an enhanced type (classic & modern technology merged) as shown in the second video. The first video shows a Class 47 testing the buffers in 2014.
Glasgow Central 2015:
This isn’t a test but rather shows an unusual arrangement – a combination of Ipswich hydraulics and modern friction style stop – its a super powered version of a buffer stop!
Glasgow Central 2017:
Its not really a buffer stop test video – just views of the Class 37 going in and out of different platforms – but at one point near the end of the video one can see why it is doing that – its testing the stations buffers!
Cannon Street 2002:
Quality not very good but shows intensive testing of Oleo hydraulic buffers following the major crash in the 1990s.
Oleo test on possibly a preserved UK railway in 2012 using a low cab diesel shunter. This location could be any number of preserved lines in the UK. Cant think of any situation where classic brake vans might be used on the main lines these days:
A seven minute video showing various tests at Bradford in 1945 with different types of buffers, some of whose names will now be largely forgotten! Such as the Edinburgh Light Type, the London & York Light Type, and the Edinburgh Heavy Type. This is part of the BFI series of free films, so head on over there to view this gem of a film!
Another from Brazil – involving a multiple unit and a faster speed:
Film from London TrackWork Inc based in Ontario.
Tests in China using wagons and what looks sort of like an Oleo style buffer but of their own design.
Slo-mo view of what happens when a freight wagon slams into a newer type of buffer stop – the Fixstop OK. Its not a hydraulic model but rather a fixed frame type. How the buffer stop copes with the collision is quite impressive.
This next one is also from India. Its an extremely good demonstration as it shows a friction buffer effectively stopping a heavy goods train at a fair speed. Not only that it pushed the train back a few feet! One of the best examples I have seen.
This is a London TrackWork demonstration, however its Japan where the demo is being shown.
This is at the Yeoung-dong Crash Test Site which belongs to the Korea Railroad Research Institute.
Short film showing the side of the buffer:
For those who want a bit more on the technical side
A video from Oleo showing various impacts, the technical data, how the different components manage their job etc.
Oleo also has a page featuring its different types of friction buffer stop.
