Midlands show is back
Support, and caution, for young
A year’s worth of
EIM
elcome to the June
EIM
and I’m writing these words just a
week or so after taking a brief break from another day
swarf-making in the workshop of the Fairbourne Railway,
to watch the first train of a new operating season pull out – it was a
sight to gladden any enthusiast.
Now in my ‘other’ role as editor of
EIM’s
sister magazine
Narrow Gauge World
I was also standing on the sea wall in
Fairbourne when the line became one of the first in 2020 to restart
services, which then was in July. As we know the hope for a return
to normality was to be dashed, but this time there’s a real feeling
that we really are on the way out of a pretty dark period.
Fans of tech-ed Harry’s ‘Behind the shed door’ column (there are fans, we’ve had letters!)
will be interested to hear that he was a pretty busy Fairbourne Railway engineer in the weeks
before reopening. His column this month focuses on a couple of specific techniques needed in
6-inch scale loco maintenance, instead of an overall round-up and to be honest he struggled
to find time to write that. Have no fear, his column will be back in usual form next time.
As ever we have quite a mixed bag of material to offer you this month, including a new
occasional series concerning the revival of a 2-inch scale Ransomes traction engine. Watch
the online auction sites such as eBay or on social media model engineering for sale groups
and such unfinished projects regularly come up – bringing another model engineer’s
abandoned dream to fruition is becoming an increasingly popular way for newcomers to get
into the hobby, especially if they have an experienced mentor to guide them. And the
successful completion of such a project often inspires the new model engineer to tackle
something more challenging from scratch, which has to be a good thing.
Meanwhile, reading about such projects, such as the Ransomes and Sam Ridley’s rebuild
of a Winson kit, can encourage others to have a go themselves. So if you’ve turned an
abandoned build into a finished model, why not write it up for your fellow readers?
Enjoy your
EIM
as we keep on that route back to some form of normal.
