Great road cars, sports cars and racing cars all have one important thing in common – total design and engineering! These are not just sports cars; they’re automotive engineering genius. With such striking features, phenomenal power to weight ratio, intelligent design and mind-blowing top speeds, who wouldn’t want to get behind the wheel?
The weather has turned positively autumnal with a drop in temperature and leaves starting to drop from the trees. At this time of year commuters across the country groan and begin to think about how often the weather is likely to disrupt their daily journey to work. Leaves on the track is frequently put forward as the major reason for causing seasonal disruption to services on our rail network, and whilst at face value the reason sounds a little far-fetched, leaves on the track are in fact, a real safety hazard.
So why do leaves on the rail network cause so many problems? There are 2 key areas where leaves cause problems:
Trains lose their adhesion as the rails become more slippy
Leaves act as an insulator and can disrupt electrical signals on the track.
There are a few reason for plating or coating busbars. Cosmetic reasons or provision of insulation are a couple but the most common reason for coating busbars is to inhibit corrosion.
Busbars are commonly made from copper, which in itself is quite resistant to corrosion but busbars are often used in environments where higher levels of protection are needed. Over time, copper oxidises and can impact the surfaces conductive properties. So plating or coating busbars, not only reduces corrosion but also improves the longevity and conductive properties of the item. Continue reading →
In 2014 South West trains introduced electrical multiple units (EMUS) on some routes from London Waterloo. This along with projects to lengthen platforms and trains on other services is just small part of an £800 million investment to improve rail services on the network. In 2015 South West trains ordered a number of Siemens class 707 EMUs for use on the Windsor to London Waterloo commuter service and the first body shell for the 707s was completed in October 2015 at the Siemen’s factory in Germany.
Last month testing of the 707s began in earnest at the Siemen’s dedicated test track in Widenrath, Germany. The state of the art testing site has been designed to test UK fleets to Network Rail standards and should keep disruption to UK train services to a minimum during the testing phase.

When it comes to manufacturing parts or components the way each one is finished reflects the quality of workmanship. If you don’t finish a job properly, then it doesn’t matter how careful you’ve been with the initial production, cutting or moulding, the end product is not going to look good. And the way the end product looks will always have an impact on saleability.
There could, of course, also be an impact on your costs. If your customer is unhappy with the finish of an order, you may have to start all over again, meaning more waste and increased costs. And there’s the health and safety aspect of poor finishing. Rough or sharp edges won’t be acceptable to your customer and may also cause injuries to those working with them. Continue reading →
