Electric bikes discussion.

Laverdaroo. Um yep, horrendously… eg search ‘eBay 304704600819‘. (£600 or so for an unused model). I never knew I needed one, simply perusing eBay and ouch - very luckily Santa imminent. Yep Steve, the tracks beneath a standing tender gets hot I read; I lazily assumed the boiler but with 100+ watts going through relatively small contact areas you may be right.

They were a very short run by Hornby (4 yrs / 2004’ish?) I think the expense, complexity, relative lack of controllability, and most of all, incompatibility with your existing layout sealed the nail. The voltage and delivery thereof, is incompatible with standard 12v locos, meaning the LiveSteam range needed their own dedicated track. Folk who run them favourably comment on the smell; you are of course poking oil and water fairly regularly into them.

It’s obvious that my love of ICEs has dwindled since we got the EV; which tbh ticks so many boxes being retired, living in the sun & with home solar. But I totally get what you say Ted wrt steam locos; esp standing on the platform as one slowly approaches - the sense that it is actually a breathing / living thing is almost inescapable. Lovely.

YouTube is spooky, and lately has been throwing up clips of large Diesel engines cranking and starting. Often it’ll be a Deltic class loco, or better still, some old girl that’s stood years and being woken up. Fascinating, esp when the video gives a walkthrough of the ‘engine room’ of these Diesel-electrics. Mrs Lobo just rolls her eyes - not a glimmer of hope there… 😂

Thats a shame but I still want one, I haven't dare look yet as TLHG is about, but I will

My brother, being a Train Ned' made sure it rubbed off on me and I always loved the steam but had appreciation for the big sooty diesels. The Deltic was and still is my favourite. I spent years being dragged about behind alsorts of stuff from Warship class engines to 08's and the small shunters that are still used today, up and down the Settle and Carlisle, North York Moors, East coast Mainline, and hundreds of hours on cold, drippy stations, waiting for summut to turn up 

   I've seen these start up videos and seen a few now, brilliant, what a din........and you gotta love the flames I had chance to go into the engine room of a running Deltic whilst somewhere or other when I was about 8 or 9. I was staggered by the sheer noise of the thing and how much wind it produced inside the engine compartment with all the belts, fans, rads etc going like buggery even on tick over. AWSOME engine!

The phrase mentioned earlier 'Spooling up' made me smirk, it was the bit you were always waiting for. Daft really but just made me smirk having a think.

Not a train nerd, but didn’t the Deltic have some weird and wonderful cylinder layout?

Yes, Deltic deriving from Greek Delta symbol, has a triangle inverted with crankshaft at each node (so one at base, two at top) each one running a set of rods/piston in vee formation, the piston crowns meeting at centre of each bore where combustion takes place ! phew 

Each piston rod etc balancing itself against its opposed assembly at compression and bottom of stroke too. Also used in motor torpedo boats i believe.
It's quite a unique configuration and very light for it's power output too as so many power stroke are dispensed within a relatively small area. One hellavu size overall though.
Can only come in slices of three barrels and six piston sectors added together.

Quite a piece of engineering overall

And, do you think I've got the timing right on this ?

Or, I've got a flat washer left over, does anyone know where this goes ?

OMG. I’m saying nuthin…😱

[andy120t]

That chap in the architecturally gives it scale. It's a monster!

Allen Millyards next project.

Interesting how these things are looked at and where the detail is located, integral or remotely.  I travelled on District line yesterday, wimbledon to nottinghill, although I'd guess the traction motors are relatively simple ? The absolute colosul miles of cabling far outweighs this aspect. Hadn't thought of it in that way before, but infrastructure outside the pure traction is immense, that in comparison to a diesel locomotive needing just rails and fuel tank to run.

The old dmu units used Leyland 680 engines

There’s a Deltic on EBay if anyone has a spare 25k

The NSU RO80 had way fewer parts than a reciprocating engine as did the rotary engined Norton. Didn't make them a seller or more reliable  & it bankrupted NSU.

There's not much needed for me to post this again https://youtu.be/QtUEPwHnxmU as example of ice indoctrination. Quad rotor wankel, so 4 rotating main parts, one crankshaft and a bunch of bearings.

They started this one at goodwood fos one year, sounds like armagedon, has wierd doppler effect in soundstage (like the noise surrounds you) and had people walking towards it like zombies, not really knowing what it was. It's a freaky noise and possibly deep in our response cortex may resemble being chased by a mad bear 
Seems like a human brain development path, to chase fear as there lives progress.  or something of that ilk.

Not a Delly but a class 50 frozen solid and blowing fire at Kidderminster. They were always the best at blowing smoke rings
