# Talk:Caltrain Modernization Program


#### Suggestions
The page could use a "current status" section to summarize the latest info about the project progress and running estimate of project completion, versus original projections.  
For example, summaries about what parts of the electrification are on or behind schedule, whether the cars being built are on schedule, and the ultimate final date for revenue service, whether on or behind schedule.  — Preceding unsigned comment added by Supernova87a (talk • contribs) 23:53, 31 May 2020 (UTC) 

@Mliu92: I think the 2021 brochure is in error about the length of a 7-car set. The older brochure indicated a car length around 85 feet, which is standard for US passenger equipment; it seems extremely unlikely that they would have switched to a much shorter car.

Thanks - agreed. It also copies the truck configuration, power output, and tractive effort verbatim from the 6-car brochure, despite the addition of (apparently) another passenger trailer with two powered trucks, so I think they didn't check it very thoroughly before posting it. I'll update the article and revert the title back to a six-car consist. Cheers, Mliu92 (talk) 00:22, 30 March 2021 (UTC)

Putting this original research here for now, as I don't have a verifiable source other than observation:

Notes:

Caltrain EMUs have a seven-car consist, consisting of two cab cars (on the north and south ends) and five passenger cars (in between)
Caltrain EMUs carry three-digit numbers on the leading (north and south) cab cars
All three-digit numbers are in the 300s
All north cab cars are odd
All south cab cars are even
The lowest three-digit number is 301
Leading elements are paired so the south cab car is one (integer) digit larger than the north cab car. I.e., if a train has 305 as the north cab car, the south cab car is 306.
Caltrain EMUs carry four-digit numbers on the middle cars
All four-digit numbers are in the 3000s
All four-digit numbers are based on the north cab car's three-digit number
The car immediately south of the north cab car uses the north cab car's three-digit number with a "1" appended to it. So for instance, the car immediately south of 305 is 3051
Four-digit cars are numbered sequentially from north to south, skipping 4 (e.g., car numbering jumps from 3053 to 3055); I speculate this is to accommodate eight-car trains in the future
Bike cars are 3xx2 and 3xx6
The only restroom (labeled WC) is in 3xx1

Updated train layout: https://stadlerrail.com/media/pdf/kcal0823e_us.pdf -- in the drawing on page 2, north is oriented to the left.

I am concerned that this article no longer meets the good article criteria. Some of my concerns are outlined below:

There is an "Overview" section which seems to be a second lead for the article. This should be combined with the lead.
There is an orange "update needed" banner at the top of the "Environmental effects" section, and an "needs update" tag at the end of the first paragraph of "specific modifications"
There is some uncited prose in the article.
Is anyone willing to address the above concerns, or should this go to WP:GAR? Z1720 (talk) 22:17, 23 November 2024 (UTC)

Hanging ropes, chains, cables, if pulled down by a uniform force of gravity, assume the shape of a "catenary curve" not a parabolic curve.     In the description of the electrical system, it talks about a messenger wire from which the conductor is suspended.    It says this is curved as a parabola.    It should say catenary curve. 73.231.66.144 (talk) 02:31, 21 July 2025 (UTC)

I've made the change. Pi.1415926535 (talk) 03:07, 21 July 2025 (UTC)
