Ok for all of you railroad buffs, those that commute on trains, and those who have an interest in "alternative mass transit", which do you think is better?
So called "light" rail?
Or so called "heavy rail"?
In case you don't know the difference, I will explain for you.
Heavy rail is your "traditional" trains, operating on standard gauge track, pulled by a diesel locomotive. Most non-Northeast Amtrak is "heavy rail. Also here in LA, we have Metrolink, which operates on the same tracks that the freight trains operate.
Light rail is what can be called a "modern trolley train".
They operate on exclusive right of ways. They are electric, which means there is usually a wire suspended above the tracks that the trains follow with a boom. Also, they are usually much smaller than heavy rail.
So which do you think is better?
Here are, what I figure the plusses and minuses for each:
+'s: Relatively small. Usually not much bigger than standard busses. Run on electricity, which means they are virtually silent in the neighborhoods they operate. Also, they put out no air pollution.
-'s: Because an entirely new line needs to be built for them to operate, from conception to revenue service can take upwards of 5 years. Add to that if there are budgetary or political obstacles. Also, once placed on a line, they cannot be "moved", unless it's to other lines-which have to be connected. Plus, the huge truss assemblies and the wires IMO makes them very unsightly and cluttered. Plus, they tend to operate relatively slowly, usually 50MPH or less.
+'s: Since they are standard locomotives and cars, they can be placed in service on existing freight tracks. It would only be a matter of constructing passenger depots, which means that a heavy line service can theoretically go from conception to revenue service in a matter of a couple of months. Plus, they can really go fast, 80MPH or faster. Plus the coaches are full sized railroad cars which means the capacity is many, many times greater than a light rail. And there are no unsightly truss or wire assemblies to look at.
-'s: Since they are full sized diesel locomotives, they put out diesel smoke, and are quite noisy. One going at full speed will create a lot of vibration as well if the tracks happen to go through a residential area. Plus, considering their sheer mass (weight, speed, inability to stop quickly), they pose a relatively much higher threat to careless vehicles and pedestrians.

Heavy rail for medium / long distance transportation between population centres.
Light rail for urban and suburban areas.
MattD, I would add that Heavy Rail doesn't have to revolve around just diesel traction. Acela, Bullet, TGV, ICE - they're all 'pantographed-up' and they don't look particularly light to me. Most new Heavy Rail links are electrified to 25Kv.

Seems I didn't answer the question properly
I *prefer* heavy rail. There's nothing like being stood at a road / rail crossing and feeling the force of a 140mph train whizz past you. Travelling on an intercity express, the views are always more interesting. I recall (some years back now) doing a special trip on the Eurostar from London - Paris - Brussels - London in the space of fourteen hours. One of my fondest travelling memories.
However, I'll always have a spot for the London Underground.

Heavy rail pays the bills, so there goes my vote. The company I work for produces switch and signal equipment for railroads. 99% of our business is with large railroads running large trains (BNSF, UP, CSX, CN, etc). We produce replacement parts for the switch machines, and detection systems for moveable-span bridges (the equipment that locks the rails in place, and tells you so, so you can send the train across).

Electric powered rail is cleaner b/c the pollution is centralized at one point, the power plant. And things like scrubbers can be put on the smokestacks to clean up pollution from the plants. So the impact is more localized.
Heavy and light rail have their own place in a mass transit system and can work well side-by-side. Look at the SEPTA system in Philadelphia for example.
Light rail comes in many more forms than Matt mentioned. Some of the newer systems, like those in Portland, San Diego and Denver are basically modern trolley cars with the overhead power. The benefit there is that the rights of way can simply be a city street. Many light rail systems, primarily subway systems use 3rd rail power. Obviously you can't use a 3rd on a streettop application, but there have to be trains designed to use both overhead and 3rd rail set-ups.
Heavy rail is usually the best choice for intra-city or long haul suburban commuting (look no further than Metra). However the limitation that I see that many of the newer cities in the Sun Belt simply don't have the pre-existing rail lines that exist in the midwest and northeast corridor to use. Plus you are at the mercy of where the tracks are, and where people actually live, as well as the freight schedules.
In the right combination, along with buses most American cities could have great mass transit systems. But there are problems with inter-city rivalries, lack of regional planning, sprawl etc... Getting land should not be as problematic as it would seem. If new highway construction projects included right of way for light rail that would solve much of the problem. And if there was as much political motavation for builing mass transit as there was highways/freeways, then getting the land should not be an issue at all.
Cost wise, light rail is not much more expensive than major city road or freeways in cost per mile, plus carrying capacity of rail is typically much higher.

a Light-rail train will be operated in a few years on the "Randstadrail" between Rotterdam and The Hague via Zoetermeer, and maybe also on the "Zuidtangent" between Amsterdam Airport and Haarlem, which is now a fast bustrack that has opened last sunday.....

They both have their place. I suppose I like heavy rail like Amtrak better than light rail because it's a more comfortable ride wheras light rail is meant for short trips within a fixed area and its seating isn't much more comfortable than what you'd find on a transit bus.
Light rail systems do look sharp though and serve a purpose.
The overhead wires here don't look too bad. Any train buffs want to guess which transit system this is?
To add to what DesertJets said about the polution, the energy generated at a powerplant is done so much more effeciently than if the energy needed was generated on board each individual train with diesel engines. Less polution for the same energy.
A metro area with a good transit system would have would have heavy rail for suburban trains, light rail for urban trains (including subway and/or eleveted trains), and busses that would strategically feed the trains.

Hi, I'm mainly a lurker here.
Let me make a correction in a definition used here. Heavy rail is NOT transit that runs on frieght lines. You are thinking of Commuter Rail. "Heavy Rail" is just another word for "metro", "subway" or "underground."
As for my opinion, I prefer subways over commuter and light rail.

Hartsfield boy is correct. Heavy rail includes subways, undergrounds and commuter rail.
In Sydney we have a massive heavy commuter rail network which is backed up by commuter buses as well. Our commuter rail lines all flow through the CBD and are electrified (have been for over 70 years) and are double deck. Many cities I note run separate subways / undergrounds in addition to commuter trains - but given the massive size and relative low density of the city we just run the suburban trains everywhere. At last count there was around 260 stations on the Cityrail network.
Also we have a light rail, monorail, commuter buses and a large ferry network. I don't particularly like public transport but at present I get the inner harbour ferry to work instead of driving - it's great. If I had to get another form of public transport it would be a suburban train.

I grew up with „heavy-rail“-tracks behind my house so you may guess my vote .
Our national railway company uses mostly electrical material here for both the passenger and their freight-trains that go cross-border so pollution is not that big an issue but for the noise – I must say that older electr.Locos.still are pretty noisy but nothing compares to the famous old „Nohab“- Diesel-locomotive.
The belgian company is always using a couple of these sound machines to pull their twice-per-night cargo trains linking Luxemb.to Charleroi in Belgium I think.
Man,in the silence of the night you can hear these thunder cans over miles !!

Heavy rail would include systems powered by Third Rail technology, that also have an exclusive right of way. Perhaps commuter trains, but I always think more of the traditional subway systems of the larger cities, and BART in the SF Bay Area.
Light rail does not necessarily have an exclusive right of way, but I always picture it as having an overhead electrical power source/pantograph.
Just a personal definition.
As an aside, does anyone know about the status of the diesel powered line that was proposed between Escondido and Oceanside California (San Diego County)?
Go to the ba.transportation newsgroup for some good old fashioned vitriol regarding heavy rail vs. light rail use.

AIRLINERS.NET CREW FORUM MODERATOR
Heavy rail is a good way to go when you have lots of rail infrastructure already in place and need a mid or long range service. It uses equipment that already exists (standard locomotives, passenger cars, etc). Prime movers could be diesel (very common) or electric (quieter, less pollution, but requires more infrastructure to be built). Light rail is used more within cities and as a supplement to bus service within the urban core. It is less "bulky" I guess you could say. Easier and cheaper to build from scratch.
I'll give an example about where I live. I live in Minneapolis. At the moment, no passenger rail service exists in the area (except for a daily Amtrak train, but that is intercity, not for commuting). Currently a light rail line is being built between Downtown Minneapolis and the Airport, extending to the Mall of America, which is near the Airport anyways. This is to supplement urban/suburban bus lines already in place. New tracks are being built for this and the equipment is all electric. The problem with Minneapolis and St. Paul is their lack of urban density once you leave the urban core. This makes it more difficult to provide really good, frequent public transportation as your cost per rider is way too high.
Additionally, there are plans to build heavy rail service to ferry in commuters from the suburbs and outlying areas. Lots of rail infrastructure exists in the region, dating from the early days of rail when it was a heavily used form of transportation, both long and short distances. These underutilized tracks are in OK shape and actually go through areas that have lots of residents. Instead of going to through the cost, hassle and controversy of tearing down hundreds of houses and building tracks for light-rail, why not use rails that already exist, have existed for generations and go where you already need them to go? All you need to do is build some train stations/park-n-rides along the way and you are set! Furthermore, you can take the buses in the area that already ferry passengers into the downtown core from the suburbs and realign them so they take those same riders to the nearest train station. With more buses to work with, you can offer more frequent service and more coverage in sparcely populated suburbs.
Just my dream. If I don't get to fly a plane one day, I want to drive a train
