Looking for a Deisel Electric...

[blagdon]

'Peaky' Tim, as a former Nottingham resident of your age (ish), happiness was any 12 cylider Sulzer loco to and fron St Pancras, especially standing by the open window of the first coach door listening to the turbo-chargers screaming up to Hamstead / Crickewood.
Mind you, screaming Valenta's on HST's going south from Leicester station also bring back happy memories.

Has anyone (like you Ralph) thought of setting up a micro group for Diesel-Electric and Diesel-Mechanical locos?  Seems to be a hole ready for filling, with some interest I perceive! I'd be happy to shovel some sticky stuff into the hole!

Tim (and anyone else with an interest),

Should I interpret that as request to set up an "Internal Combustion Powered Model Locos." board?

John.

That's a "Yes please" from me John.

For me the answer would have to be "Yes!" D/E and D/M (and I suppose D/H -once I have figured out how to do it...) would be an interesting place to be.  I personally believe that a "Live Diesel" model is easier to build than a steam loco.  The main problems will always be those of starting it and cooling it whilst running. I have I believe cracked most of the design problems with the use of "Live Diesel" -it would be interesting to see other peoples "take" on the issues involved.

Starting and cooling are not big problems. They have been solved many times over by quite a few modellers; mainly in G Scale. If you Google "live diesel locomotive" you will see several.

The really big problem is that nobody has managed to make them sound like the prototype; they all sound like a lawn mower on rails. Gauge 3 modellers tend to be quite particular about accuracy and realism. The real challenge is getting a live diesel to sound like the real thing.

Errmmm I beg to differ.... I did the maths (and actually they did turn out to quite nasty). The amount of cooling required for a small G1 model can be coped with a simple fan and provided the model is not supposed to run for more than about 10-15 minutes -then an 8cm @240 Litres per minute fan can (just) keep a finned 3.5cc aero engine within bounds, (i.e. below 60C). The amount of waste heat that my engine has to dissipate is 300 Watts. This is a rate of flow of 1.2 Litres per minute with a drop of 15C across the radiator.

Permit me to suggest to the moderator that this posting is transferred to a new thread of "Engines and cooling" under the new microgroup heading of 'Internal Combustion Powered'? (and that John opens this new group when he is able, recognising the vast calls upon his time to monitor all this traffic traffic and build models!!)

Tim
