does the london underground uses a car type brake pedal for stopping an underground train and does underground trains uses a car type steering wheel for steering please let me know

Yep, it's hard work steering around those tight bends, and don't get me on about the Clutch on the C stock, luckly the D stock has an automatic gearbox.

Does anyone else find balancing all the wheels on the thin strips of metal a problem?

(Just in case you're being serious)
Trains don't have steering wheels - they simply sit on the lines and go wherever the lines take them. Points are used to send the train down different branches when you reach a divergence point.
I believe there are some train systems in the world that use the idea of steerable axles to give better turning ability and simpler points systems - someone told me the DLR uses something like this... is this true? Obviously all controlled by the computers... not a driver.

Yep, it's hard work steering around those tight bends BTW it is a common practical joke Moscow Metro drivers play on unenlightened but curious passengers - the parking brake handle in E-series cars looks like a steering wheel on the ship. Unfortunately, with ongoing withdrawal of E stock, scope of that joke becomes more and more limited...

Another favourite was to tell passengers that yes, those weels are what you use to wind the spring that powers the train. ;D

I'm never asked, but I doubt I'll resist if someone asks . ;D Never heard of that. BTW some locos have controllers that look like a steering wheel (e.g. that TE116 diesel loco cab)...

Ayup, you can see them on some Swedish rolling stock too -the class T44 diesel locos, for example. One thing, though: On ex-Soviet/Russian "steering wheel" controllers, does a certain position correspond to a certain setting (i e "4'o clock= Run 3"), or do they use a system "notching up/notching down" positions? In Sweden, both styles have been used. I know that India Railways apparently consider the "notching up/notching down" style their standard. I have seen a few cab ride videos from IR where the driver is really working the wheel back and forth to to notch up a WAM 4P DB 6P all the way up to notch 34. Vroom!

The handbrake apllier on the old "Q's" was like a ship's steering wheel too with the addittion of a hand grip stick out like you get on some lorry steering wheels. They used to call it the "Barrel Organ".

Don't BR MKI EMUs have a similar contraption? (Handbrake wheel looks like a ship's steering wheel)

Yes, they do/did. As did most earlier-generation stock all over the world. The wheel handbrake was one of those universal solutions that were used almost everywhere.
As a side note: Did/do LU use any special method or device to indiate that a vehicle was handbraked? On our older stocks, there is/was a little metal sign saying "handbraked" or inverted parkign brake manually applied"that we were supposed to put in the offside cab window of the car.

:(The handbrake on 1938 stock on the Northern and Bakerloo was a weird contraption. Imagine you are looking at the back cab wall on the offside. There was a large black lever, very akin to a the levers in a semaphore signal cabin. This lever was attached the bottom in a similar way too and had a very very strong spring to keep the lever in the"off" position. About four fifths toward the top of it was a retaining bar fastened to the back wall at each end, Just above that was a worm screw with, at the right hand end, a turner exactly the same as you get on a carpenters bench vice. You wound this round and the worm screw would bring the lever over towards the centre of the cab and the handbrake wouldd be applied as you did so.
Applying the thing was bad enough but releasing was downright dangerous. Fastened to the retaining bar was a spring loaded pawl which stopped the spring on the lever from pulling the brake back to release as you applied it. Now the "official" method of releasing the handbrake was the to grab the big lever with your right hand and pull very slightly to the right and hold it tightly there. Then you were supposed to pull the pawl with your other hand let the lever go slowly towards the release position holding the pawl all the while.
Nobody ever did this however as it was bloody hard work holding the lever AND the pawl against the springs. So the trick was to take your motormans or guards key and yank the pawl handle back sharply. The bloody lever would fly back to "off" like a Guillotine with a loud bang. You had to remember to keep your hands well away from the contraption during release as some men had lost fingers by holding the retaining bar when releasing the handbrake.
I will see if I can find a picture of this device and post it.

Obviously all controlled by the computers... not a driver. Some Japanese bogies use a 'link-type forced steering bogie', where the natural bogie rotation on curves is used to operate linkages that will shift the axles to a better alignment with the true tangent of the curve. No computer control necessary. See: www.jrtr.net/jrtr18/pdf/f52_technology.pdf(from the excellent Japan Railway & Transport Review) Russ

does the london underground uses a car type brake pedal for stopping an underground train and does underground trains uses a car type steering wheel for steering please let me know It appears that we haven't directly answered your question. Most people who come to forums such as this are usually from countries where railways operate. I've just discovered that perhaps you're not as familiar with them as most people. Brakes on trains are usually air operated. Here's some info on an earlier version of one type.Trains are not steered by the driver. That is done by the track and the wheels. Points with switchable blades are used to change tracks. I'm working on a railway technology website at www.piccadillypilot.co.uk/railtech/ It's only got one page at the moment but keep checking

The former, that is, a certain position correspond to a certain setting. Valid at least for all locos manufactured by 'Luganskteplovoz'. Source: a person from the photo .
