<p>The driver of the 2G62 1415 Maesteg to Cheltenham Spa service surrenders the single line token for the section from Maesteg to the signalman at Tondu, having just passed signal TU9 - which protects the junction here. The line to the right is the disused Blanegarw branch (though a siding with loop line remains in use).  The line heading to the bottom left is the freight only line to Margam,
</p><p>This four way junction - complete with a fine array of semaphore signals is a fascinating location.  An excellent description (with good photos) of the signalling systems here can be found at &lt;a href="<a rel="nofollow" class="external free" href="http://roscalen.com/signals/Tondu/index.htm">http://roscalen.com/signals/Tondu/index.htm</a>" rel="nofollow"&gt;roscalen.com/signals/Tondu/index.htm&lt;/a&gt;

The line from Margam is occasionally used as a diversionary route for freight trains when the line between Port Talbot and Bridgend is closed.  On these occasions trains approaching from the Bridgend run on to the Blaengarw loop, where the locomotive runs round its trains, ready for the journey to Margam (and vice versa).  A photograph by Stuart Warr illustrates this well &lt;a href="<a rel="nofollow" class="external free" href="https://www.flickr.com/photos/123410911@N03/15643428463/in/photolist-pQmEgR-8szkfH-owxC4q-8zfwUD-oUaBE6-9eLvpR-qM9aRR-8RkhSB-8RopEb-8RkhK6-muNihj-b9B3J6-oTEZyK-rkZRQ2-bopVcg-8PUzox-bopTJ2-rkTpQu-fTGC5c-e9q9oC-7r8aM7-pDuQiH-oBb8JG-pCPoHg-99woKs-bsUpYU-e9ve1s-7nwhM3-bsHFHY-8RopK3-wehzxf-8RknWe-w8Rut8-8Rknyx-8RknFg-e9fWiV-8Reowk-7qiGGE-8zfx2p-e6S88c-bQtVB6-bzoNqw-eoNTnR-9RU1uS-abnr4Z-8AparP-c7JThE-dfrHBL-oP3pWR-dVRDbM">https://www.flickr.com/photos/123410911@N03/15643428463/in/photolist-pQmEgR-8szkfH-owxC4q-8zfwUD-oUaBE6-9eLvpR-qM9aRR-8RkhSB-8RopEb-8RkhK6-muNihj-b9B3J6-oTEZyK-rkZRQ2-bopVcg-8PUzox-bopTJ2-rkTpQu-fTGC5c-e9q9oC-7r8aM7-pDuQiH-oBb8JG-pCPoHg-99woKs-bsUpYU-e9ve1s-7nwhM3-bsHFHY-8RopK3-wehzxf-8RknWe-w8Rut8-8Rknyx-8RknFg-e9fWiV-8Reowk-7qiGGE-8zfx2p-e6S88c-bQtVB6-bzoNqw-eoNTnR-9RU1uS-abnr4Z-8AparP-c7JThE-dfrHBL-oP3pWR-dVRDbM</a>"&gt;www.flickr.com/photos/123410911@N03/15643428463/in/photol...&lt;/a&gt;
