Welcome, Guest

Engine Builders' Group

Turbo-generators are the main focus for this months discussions.
 
We’ll start off by looking at a miniature steam turbo-generator that was designed to power the riding lights on typically  5 in gauge steam locomotives.   Bob Walker will be discussing the tooling used by a long departed fellow member of Malden and District MES’ with a particular focus on the electrical generation aspects.   Mike Tilby hopes to join us on line to offer advice about the challenges of extracting power from small scale steam turbines. 
 
For the second part of the meeting, Jerry Burchell will be discussing the challenges he’s been facing in designing and building his 5 inch gauge gas turbo-generator powered locomotive.
 
Finally, we’ll take a look at work on the table and discuss the topics for future meetings.
 
As usual, the meeting will be open to distant members wishing to join in our discussions on line.   The URL for joining the meeting has been e-mailed to members
 
The proceedings will also be video recorded and made available, together with relevant notes, on the SMEE website a few weeks after the meeting.

Talk – Rail Vehicle Testing  

by Dave Bower

Dave Bower joined the British Rail Testing Section based at the Railway Technical Centre in Derby at the end of his apprenticeship, and spent most of the 1980s and 1990s testing all types of rail vehicles.  In his talk he will look at an area of the railway industry that is not well known about; drawing on experience from his railway career to bring to life the world of railway vehicle testing.

Static and on-track testing provides evidence to ensure the safety of train operations, including keeping the train on the track, stopping safely, the structural integrity and an acceptable passenger environment.

He will focus on British Rail practice during the 1980s and 1990s to describe and understand why, and how, acceptance testing was carried out for new or modified Wagons, Passenger Coaches, Locomotives, On-Track Plant, and Road-Rail vehicles.

Talk – Locomotive Wheel  Balancing Little and Large

by Bob Bramson

Balancing locomotive wheels is a discipline that is virtually unknown about in model engineering circles. The talk will review the prime causes of imbalance and explain the technique developed to mitigate the force inputs to acceptable levels in full size, and the read-over to miniature practice. A short discourse is also included to illustrate the causes of derailment, another area of railway engineering of which model engineers generally have very limited understanding.
