[edit] Requested move

The term "Commuter rail" seems to be primarly used in North America, and be different from short-distance train service elsewhere. I propose that this page be renamed to it (instead of having the term redirect to Regional rail) and the info moved.

If so, the following list of links should be directed to the proper article:

Add *Support or *Oppose followed by an optional one sentence explanation, then sign your vote with ~~~~

It was requested that this article be renamed but there was no consensus for it be moved. Dragons flight 00:28, 15 October 2005 (UTC)

[edit] Discussion

Any?

I eliminated a number of rail systems that were listed on this page because they were not commuter railroads, as follows:

Some systems have been left on the list that are better known for their metros (i.e., the MBTA) but they do operate commuter rail as wel.

[edit] Regional rail/commuter rail

Commuter rail redirects to the article Regional rail; since that article is more detailed and less geographically-specific, perhaps some sort of merging is in order?David Arthur 21:59, Feb 6, 2005 (UTC)

The regional rail article seems to be directed at systems and equipment we generally do not have in North America. For example, "Commonly they are based on diesel multiple units (DMUs), which are self-propelled, bidirectional, articulated passenger rail cars with diesel engines, electric generators and electric motors located below the passenger compartment (strictly speaking, these are diesel-electric multiple units, or DEMUs). In some areas with electrified rail, electric multiple units (EMUs) are used. Electric and diesel-powered multiple units are almost invariably equipped with control cabs at both ends, which is why such units are so frequently used to provide commuter services, due to the associated short turn-around time."

[edit] Overgeneralizing about 'Northeast' vs. rest of U.S.

"Passenger rail outside of the Northeast is infrequent and rarely used relative to networks in Europe and Japan." Not to quibble, but this common over-generalization ignores the huge commuter rail system in the Chicago area.

[edit] Split

Can we split the "under construction" and "proposed" tables? They're two very different things. bob rulz 17:01, 8 August 2006 (UTC)

  • Support - OR add a column with the project's status, "proposed", "being studied", "requesting funding", "under construction", etc. --MrHudson 05:11, 10 April 2007 (UTC)

[edit] Commuter Rail Service Patterns in the USA.

I have noticed that regional commuter rail service patterns would be, typically, three trains into the city in the morning and three trains back out in the evening only, even on reasonably short runs. Generally locomotive hauled trains are used. Even major routes such as Harrisburg -Philadelphia only have a few, irregularly timed trains per day.

Viewing this from the UK seems strange for several reasons:

If say four round trips were done in the morning and four round trips in the evening, then only two train sets could be used for all four round trips, saving traction and crewing costs, and providing eight services each way instead of three, with one less train unit.

Also, if you have the train sets why not make the best use of the asset of the trains and stations and run a service all day Mondays to Saturdays rather than have them hanging around in sidings all day?

Also why use loco hauled trains, even for brand new lines such as Utahs Frontrunner, rather than a diesel multiple unit which can turn round at terminals in a few minutes, enabling more trains to run or less trains to run the same service. DMUs generally also have better acceleration as they have engines under each coach rather than one traction unit on the whole train. I saw that San Diego are going to use Siemens Desiro DMUs for their new Sprinter service to Escondido but the wikipedia article calls this "light rail" which confuses me. Light Rail is a tram or trolley. Siemens desiros are heavy rail trains and here in the UK we use them for 110mph heavy rail intercity services between London, Southampton and Weymouth (140 miles) running at half hourly intervals all day.

I am basing the comments on non metro/subway lines outside New York, eg Metrolink, and the Harrisburg to Philadelphia service etc where surely an hourly or half hourly interval service to Philadelphia would attract a lot more passengers? A service of one or two trains a day would be the kiss of death on a line in the UK and even 7 a day would not attract that many passengers and is the sort of service you get on a remote branch line.

I'm basically curious and wonder whether someone could explain these questions and perhaps even add the answers to the article.

Since visiting Pittsburg some years ago, I have often wondered why a service using something like four car siemens desiro units with only two crew as in the UK, one driver and one guard, plus perhaps an attendent wheeling a snack trolley along the train, could not be used to run a two hourly Pittsburg-Philadelphia service servin major intermediate towns, some linespeed improvements to 100mph at least would be needed to offer decent journey times, but the tracks are there and the stations are there and fully staffed. It really astounded me to find a fully staffed and functional major city station at Pittsburgh with only two trains a day.

The vast majority of North America’s rail lines are owned by the private freight railways, who are generally reluctant to hand over any more paths to passenger service than they have to, so timetables are therefore limited. Commuter railways often compensate for this by running long, double-decker trains, but it still is difficult to make the service appealing to casual users. Your second question is related to the first: in the name of safety, any passenger train sharing tracks with freight trains must be built very heavy, a regulation which all but outlaws multiple-unit trains. The only practical use for them is under light-rail rules, which is why Ottawa’s Talents and San Diego’s new Desiros are limited to slow local services despite being capable of much more; inter-city, commuter, and regional services (if they exist at all) are almost exclusively drawn by locomotives. David Arthur (talk) 19:09, 3 January 2008 (UTC)
Thanks David, this will surely become a growing issue as oil and therefore gas(petrol) prices continue to rise. Am I right to assume that many of the lines are only single track and those that are double track have very long block sections?. The safety rules for passenger trains sharing with freight seem a bit odd. Desiros etc. share with heavy freiht trains all over europe. Is this because US freight trains are exceptionally heavy (athough european freights are pretty heavy too in some cases) or because signalling standards differ? Kerripaul (talk) 10:28, 4 January 2008 (UTC)
Single track is indeed much more common in North America than in Britain, as are level crossings (some of which do not even have barriers or lights). The safety rules are indeed odd and counterproductive; while North American freight trains are indeed heavier than British ones (take a look at this picture of Class 66s being delivered to see how much larger the Canadian locomotives are), the limitations have more to do with poor signalling systems and even more to do with politics. Who wants to vote against ‘safety’? David Arthur (talk) 16:23, 4 January 2008 (UTC)
