Having met and discussed the Beach Head project with one of its leaders, his words came to be summarized as such; We weld fabricated the cylinders because at the time it was thought casting the cylinders would be cost prohibitive and too complex. Now that there are many new build projects, heritage locomotives repairs with new cylinders, and the pattern making technology has advanced to one off 3D foam prints, I wish we had just waited a bit longer and gone with the casting process. Its cheaper that way now and avoids all the thought about welded assembly and tricky issues with warping -Fred Bailey. I cannot remember every word he said to place it as a quote, but this is as close as I can remember the two year old discussion.

A good example of that last bit he said can be seen in the build log for Lyn (topic locomotive) around the time they got to machining the welded assemblies. If I recall correctly, one side was incredibly close to too small due to warping and miscalculations in material placement/length.

Take what 2 cents you find in his words, each project can benefit or find drawbacks in either method of production.

Film off Youtube of it on test - shame about the microphone wind noise...

A bit delayed but finally its debut connected to its tender. Finishing work is still in progress, it looks to me as though parts are missing on the steam dome but I will defer to the experts. I will also defer to the experts as to whether this locomotive is practical or sexy, as per the recent discussion of new-build power. As was noted on facebook, there are now 30 new-build steam locomotives either in service or under construction in the UK: https://www.facebook.com/bluebellrailwa ... xGyJmi9dBl

'Beachy Head' Emerges!
A historic day for everyone at The Bluebell Railway. New build Marsh Atlantic No. 32424 'Beachy Head' was transported from its shed at Sheffield Park yesterday afternoon and was partnered with its tender for the very first time this morning.
This is an incredible achievement by the Atlantic House team and everyone involved with this fantastic project. The reality of seeing an LBSCR Marsh Atlantic is very much reaching the final stages.
The locomotive has now been moved into the maintenance shed where the commissioning work will now commence to bring 'Beachy Head' into service.
Here are a couple of photos of both yesterday and today, showing 'Beachy Head' at Sheffield Park."

"32424 'Beachy Head' Moves For The First Time!
An incredible moment for everyone involved at The Bluebell Railway. Today, 'Beachy Head' passed its boiler test at Sheffield Park and made its first movements around the yard.
Further news will be shared in due course regarding 32424, however further testing is required before the locomotive will enter service.
Congratulations to everyone involved in making this a reality and a huge thank you to Neil Glaskin for sharing this moment with us!"

This thread is becoming a bit cluttered, but another new build locomotive debuted recently in the UK, 6880 Betton Grange (you don't need a facebook account to watch these videos, just click the grey X in the upper right hand corner and you can bypass log-in):

"A newly-built steam locomotive welcomed its first passengers at the weekend.
Hundreds of steam enthusiasts travelled on board the 6880 Betton Grange at the Cotswold Festival of Steam.
It is the first Grange class locomotive to be constructed since production stopped after the Second World War.
(Footage from GWSR)"
