Hi Old Moonraker, and welcome to Wikipedia! Thanks for joining the coolest online encyclopedia I know of. I hope you stick around. You'll probably find it easiest to start with a tutorial of how the wikipedia works, and you can test stuff for yourself in the sandbox. Check out the simplified ruleset. When you're contributing, you'll probably find the manual of style to be helpful, and you'll also want to remember a couple important guidelines.

1. Write from a neutral point of view
2. Be bold in editing pages
3. Use wikiquette.

Those are probably the most important ones, and you can take a look at some others at the policies and guidelines page. You might also be interested in how to write a great article and possibly adding some images to your articles.

Be sure to get involved in the community – you can contact me on my talk page if you have any questions, and you can check out the village pump, where lots of wikipedians hang out and discuss things. If you're looking for something to do, check out the community portal. And whenever you ask a question or post something on a talk page, be sure to sign your name by typing 4 tildes like ~~~~. Always sign the talk page, never the articles.

Again, welcome! It's great to have you. Happy editing!May the Force be with you! Shreshth91($ |-| r 3 $ |-| t |-|)

Why exactly is a continueous stream harder to sustain in a road vehicle? Why aren't deadman's brakes as common on road vehicles as on rail vehicles of even similar size and weight, for example, modern trams do have some sort of deadman's but for some reason, not busses, inconsistant, isn't it?

Actually, older trams generally did not have deadman's brakes, but in the 1930s, some justuctions (I don't know whether or not the HMRI was one of them) did make them mandantory. Here in Melbourne, all our trams in regular service have deadmans', although busses and trucks in Australia invariably having nothing like this. Our Zs, As, and Bs have acclerator and brake pedals just like on a road vehicles, but have an additional pedal which drivers must depress to mobilise the vehicle. If this pedal is released after the tram has started moving, the track brakes are applied, unless it stops before it is released. This type of deadman's could be emplyed on a road vehicle if there is no clutch pedal in the way. But who needs a clutch pedal anyway? It is perfectly possible to intergrate a clutch trigger into the gear lever, or have automatic clutch operation (why aren't they more common if thery are so cheap to instal). If a centrifugal clutch (which automaticlly disengages when the engine is ideling) is fitted, then you don't really need a clutch pedal, clutch handle or clutch button anyway (It is possible to make all the gearchanges without disengaging the clutch). The use of a freewheel similarly eliminates this need, although doesn't allow for engine braking, unless it can be locked, or revearsed. Or what about those high tech transmissons like tiptronics, selespeeds, sensodrives and twin cluch gearboxes such as Direct shift. Another idea can be found on this page. Also, there is a proposal to add penalty switches to cruise controls. Myrtone@Moonraker88.com.au

That was quick - thanks! — Preceding unsigned comment added by Moonraker88 (talk • contribs)

Hey, you're welcome. btw, I saw the page for James Samuel (engineer). Usually it's not necessary to create such pages, unless there are two people with the same name and a disambiguation page is required. I'd suggest listing the page for speedy deletion by simply inserting the {{db-author}} tag to get rid of it. At your discretion, you can create a redirect, instead.--Kchase02 T 06:43, 19 June 2006 (UTC)[reply]

I'll try that tag. Thanks again. Moonraker88 06:50, 19 June 2006 (UTC)[reply]
