The Barry Docks ABP to Dollands Moor service from Wembley to Dollands Moor 6B41 on 5 May 2014. It was also photographed by Edward Clarkson later on route at Sevington near Ashford (&lt;a href="<a rel="nofollow" class="external free" href="https://www.flickr.com/photos/60771112@N07/14111370611/in/faves-99279135@N05/">https://www.flickr.com/photos/60771112@N07/14111370611/in/faves-99279135@N05/</a>"&gt;www.flickr.com/photos/60771112@N07/14111370611/in/faves-9...&lt;/a&gt;). When it runs this service is typically hauled by a class 66 from Barry Docks to Wembley where another class 66 or a class 92 takes over for the last part to Dollands Moor. In this case class 92 number 92042 took it on.  5 SNCF-registered NACCO Polybulk covered silicon hoppers (in order numbers 37 80 0699 001-3, 37 80 0699 009 7, 37 80 0699 004-8, 37 80 0699 012-1 and 37 80 0699 008-9) were attached behind the intermodal 28 containers mounted on flat wagons  (2 per wagon). One of the intermodal wagons was thought to be number 33 87 490 9394-8. The empty hoppers are used to transport silica sand from either Amberieu or Notre Dame-de-Briancon France to Dow Corning's silicon-based materials manufacturing plant at Barry, Wales, where it is used to produce semiconductor silicone polymers.  In France the train passes Hazebrouck (see &lt;a href="<a rel="nofollow" class="external free" href="http://1.bp.blogspot.com/-D3mPhzxDR5w/U44E8r8xV3I/AAAAAAAAefo/5ROBTf1OT9w/s1600/M%c3%a0J+mardi-2+">http://1.bp.blogspot.com/-D3mPhzxDR5w/U44E8r8xV3I/AAAAAAAAefo/5ROBTf1OT9w/s1600/M%c3%a0J+mardi-2+</a>" rel="nofollow"&gt;1.bp.blogspot.com/-D3mPhzxDR5w/U44E8r8xV3I/AAAAAAAAefo/5R...&lt;/a&gt;(4).jpg).
