yes it is another rail thread :rolleyes:


anyhow. whats this red wheel for?
couldn't find a decent pic so here's an Eiretrains link

the outside wheel for nice days :pac:

I think it's the hand brake, the 141/181s have a different system in a similar spot that look like a torque bar. It's mainly for when the loco will be parked in the same spot for a long time incase it's normal brakes fail.

It's to close the bulkhead doors in the event that it gets hit by a torpedo.

That's it. When the loco is parked up the wheel is turned to apply the brake. The baby GM's have the torque bar and chains to apply the brake,has to be pumped a few times to apply the brake.

Here's a pic of it:http://andyskinner2887.fotopic.net/p64458062.html

Now that I have a plausable real answer (above) i think it's time to come up with the most outlandish suggestion

foggy_lad

its for turning off the rain

It's the dial of a CIE time machine. One 360 degree turn will bring you back to a GSR 1925 network with 800's running the Dublin-Cork express,Hunslets and MKII's on the Dublin-Belfast,C Class on the spin to Valentia harbour,double headed 121's on the Rosslare. AAAAAAAAAAAHHHHHHHH,I can dream!:)

steamengine

Just looked up some of the specs - GM 2 stroke V12 turbocharged engine giving out 2,250 bhp. top speed 90mph and an amazing max tractive effort of 65,000 lbs. Serious bit of kit - now the wheel !

Simply a spare in case of a puncture !:)

Transportuser09

Its for a clockwork mechanism for winding up the engine in the case of fuel starvation. Makes it good for a further 90 minutes use without rewinding.

It controls the flux capacitor for the turbo charger.

Cookie_Monster

it changes the height of the train so taller drivers can fit in

Hungerford

It's a cloaking device to be deployed whenever Dick 'my best friends are railcars' Fearn's around.

CIE installed many useful devices on their former locomotives such as these "nippers" which use to snap at members of the public that got too close to the engine cabs.

Comedy phail.

I'm almost certain that wheel is a manual handbrake.

Would you find a manual handbrake on a modern DMU / DVT?

Nope, well not on the outside anyway.

Anyway the wheel on the side, one only, is for the Hand Brake (lefty-loosey & righty-tighty)

It only applies one brake block to two wheels (the trailing wheelset closest to the hand brake).

Well that's official, the secret use is;
When you turn it several times to the right, and then a few to the left, it begins cold fusion, and thus solves the world energy crisis.
Unfortunately IÉ burned all the old manuals in one of their "I Hate Locomotives" days for the new management.:D

There's aparently another combination that destroys all the Railcars in 150 mile radiius, this was burned as well! such a shame.........

The 201s have a manual handbrake too but it's operated by a button in the cab rather than a chain or wheel.

Two strokes diesels are used in trains because they have a far higher power to weight ratio then a four stroke engine of the same size. This is because they have twice as many power "strokes" then a four stroke engine. Two stroke diesels are used in almost all heavy movers - ships, trains etc

However they require some sort of a compressor to compress the air going into the cylinders, usually in the form of a turbocharger or a geared supercharger

IE have decided to use the flux capacitor and use the 071 for time travel back to the 80's

True, but some notable engine companies have phased out two-strokes (even petrols) because of pollution (it's easier to make a clean 4-stroke), with other makers heading the same way.

Are there emissions standards that apply to trains as there are to road vehicles?

I doubt there are, due to the small volumes of locos. Where you have millions of cars the small amounts of pollutants multiply. While a loco might belch out smoke, there are very few of them.

I'd reckon any movement toward fuel efficiency is done for economic reasons rather than environmental.

The EMD 645 and 710 series (071 class and 201 class) are indeed two stroke, but remanufactured 645s and new 710s (as in the MotivePower MP36 and MP40 commuter locos) are certified as US EPA Tier 2. They aren't lawnmower engines.

2 stroke petrol engines which run on a petrol/oil mix are definitely polluters as can be seen by their smoky exhausts. This is due to incomplete combustion of the lubricating oil. 2 stroke and 4 stroke diesel engine lubrication is seperate from the fuel injection system and with timely maintenance procedures there really should be no visible signs of incomplete combustion of fuel, as in smoky exhausts, particularly when under load. Manufacturers do issue Nox emission specs for their engines.

There are always going to be emissions issues with diesel in compression ignition engines, and treatment of exhaust is the only solution. In cars Diesel Particulate Filters, Adblue and even exhaust plasma reactors are all used to varying degrees of success.

Tier 2, as applied to locomotives is not the same as Tier 2 for cars. Tiers 0-2 do not require exhaust treatment, which is a bad sign.
