Hello lee, are electric locos welcome?

Neil

[ruston165Participant @ruston165]

Of course Neil, all welcome, would be good to see something other than steam in 3 1/2 running.

Great, I'll put it in my diary – no promises, but I'll do my best to get along. It's a raised track at the GCR sheds as I remember?

Neil & Lee I hope to see you there, last year I went to Leyland and had a great time for me this is half the distance!

I can not have you with the only diesel I will bring my new toy (bought form the classifieds last year) This is my first posting hate computers the pictures upside down.

Lee, the website doesn't give any times – is there any more information you can give?

For anyone wondering this is the venue from the NSMEE site:

[ruston165Participant @ruston165]

Hi Neil, it will be from 10am onwards, the site is locates at Great Central Railway North at Ruddington. On site catering. We are also doing a BBQ on the saturday evening for anyone staying later. Everyone welcome, and if bringing a steam loco please bring boiler certs.

In an unprecedented move, I have invested in a brand new 7Ah battery actually meant for cyclic motor use rather than my old worn-out burglar alarm batteries. I've also checked out the 1:111 gradient and gambled on my high gear ratio

Be honest Paul it's from the Antipodes isn't it

I've just come back from a great half-day.

Scalextrix fans will be delighted to know Paul's 08 has 'magnadhesion' as the photo shows, but it didn't work on the alloy rails. Paul kindly let me run round the track with his train – it was like being at Alton Towers with tension of worrying about derailing the loco with a full rake of wagons!

My battery decision was a good one – I did three laps or nearly 1 1/3 miles and the battery was still full of life. Although it slowed down a bit on the gradients, my problem was wheels slipping not grinding to a halt, gentle starts worked OK, so it was capable of pulling me up 1 in 110 on 50% power. I would guess that it would happily do a few more laps at least. The headwind was worse than the gradients – when I was stopped on a gradient one gust had me rolling backwards!

My very simple driving trolley worked well, especially the very simple rubber block suspension, but I think a bit of padding is needed on the stirrups as they started to dig into my legs.

I think I will simplify my controls. I discovered that I've fixed it so the back-emf brake can't be put on when you are in 'neutral'. That said the braking works much better now I have a truck with pads that give no danger of fouling the buffers.

P.S. they have four(!) bridgeports…

[Neil WyattModerator @neilwyatt]

Just measured the off-load voltage of the new battery, it's has some 4-5 hours rest and it is putting out 12.61V which, depending on where you look, suggests it has only given up 10-25% of its capacity.

Someone at the track said a 7 1/4" loco did 6 laps on two of these size batteries without slowing down.
