The final rule codifies train crew staffing rules at a federal level, ensuring that freight and passenger rail operations are governed by consistent safety rules in all states. This is an on-going issue as Ohio, Virginia, and Colorado, among others, have recently considered legislation to require two-person rail crews. In addition, the final rule contains some differences from the initial notice of proposed rulemaking in how it treats freight railroads, especially Class II and III freight railroads. In limited cases, the rule permits exceptions for smaller railroads to continue or initiate certain one-person train crew operations by notifying FRA and complying with new federal safety standards.
Under the Train Horn Rule (49 CFR Part 222, issued on August 17, 2006), locomotive engineers must begin to sound train horns at least 15 seconds, and no more than 20 seconds, in advance of all public grade crossings. If a train is traveling faster than 60 mph, engineers will not sound the horn until it is within 1/4 mile of the crossing, even if the advance warning is less than 15 seconds. There is a "good faith" exception for locations where engineers cannot precisely estimate their arrival at a crossing and may begin to sound the horn no more than 25 seconds before arriving at the crossing.
Train horns must be sounded in a standardized pattern of 2 long, 1 short, and 1 long blasts. The pattern must be repeated or prolonged until the lead locomotive or lead cab car occupies the grade crossing. The rule does not stipulate the durations of long and short blasts. The maximum volume level for the train horn is 110 decibels, and the minimum sound level is 96 decibels.
Intermodal rail yards are critical components of the goods movement sector. At these facilities, cargo is transferred between trains and another transportation mode such as trucks. In May 2018, the South Coast AQMD Governing Board directed staff to pursue both rulemaking and voluntary measures to implement the 2016 AQMP Facility-Based Mobile Source Measure MOB-02: Emission Reduction at Rail Yards and Intermodal Facilities. Overall, the focus is on identifying actions to address emissions associated with intermodal rail yards and to minimize public health impacts in surrounding communities.
In 2021, following the announcement of two new intermodal rail yards to be potentially built within the South Coast AQMD jurisdiction, staff began to focus on developing a rule which seeks to address NOx and particulate matter emissions from new intermodal rail yards through at-scale zero-emission infrastructure planning and installation, while continuing to pursue both regulatory and voluntary approaches for existing rail yards. The parallel efforts are reflected in the 2022 AQMP, where MOB-02A is the control measure for new rail yards and MOB-02B for existing rail yards.
Under a Notice of Proposed Rulemaking (NPRM) published today, transit agencies nationwide would be required to create a protection program geared at personnel who work on or around the tracks, implement comprehensive training for workers, and ensure that unsafe acts and conditions are reported. The proposed rule would apply to rail agencies and state safety oversight agencies (SSOAs) that are tasked with overseeing safety, marking a significant step toward protecting those working on transit railways.
According to data reported in the National Transit Database, between January 1, 2008, and October 31, 2022, 22 workers were killed and 120 workers were seriously injured in rail transit roadway safety events.
"This rule will ultimately save lives," said FTA Acting Administrator Veronica Vanterpool. "Once this rule is finalized, it will support safer conditions for workers who perform critical tasks that keep transit operating efficiently and safely."
FTA is also seeking feedback on the level of participation that safety committees, which are established by the rail transit agencies, may have in the proposed rule, including their involvement in approving, monitoring, or overseeing the implementation of a rail transit worker protection program.
FTA encourages members of the public, transit agencies, State Safety Oversight Agencies, unions, and other interested parties to submit comments on this proposed rulemaking for the transit industry to the Federal Register comment docket, which will be open for 60 days until May 24, 2024.
I'm able to get it to work with the following project layout. The obj files are in the assets folder, the cga file is in the rules folder, and the cej file is in the scenes folder. Then I open the cej file and apply the changes described in my first post ( ). I did not have to change the cga file.
If you try to open the scene file (tracksScene.cej) in CE 2015.2, then the railroad tracks do not look curved. Is this what you're talking about when you say it's not working? This might be because this code was written for an earlier version of CityEngine, and things have changed since then. To fix this, you can select all shapes (right click in viewport -> Select -> Select All) and then make the graph segments curved by going to Graph -> Set Curves Smooth.
For the missing texture files, I'm guessing you are referring to the warnings generated about not being able to find the .mtl files. This is ok because it doesn't affect the generation of models in the scene, and you don't need to do anything. There are no texture files (mtl files) associated with these obj files. If you want to make these warnings go away, you can edit the obj files and remove all the lines that contain anything to do with "mtl".
CARB has developed and implemented measures to understand and reduce locomotive and railyard emissions in California, including studies, regulations, enforceable agreements, and funding of clean technology.

On April 27, 2023, CARB approved the In-Use Locomotive Regulation. The Final Regulation Order and additional information about the Regulation can be found on our Rulemaking Page. Summaries of the new requirements for locomotive operators are also available on the Locomotive factsheet website.
The US Department of Transportation (USDOT) is suspending a rule that allows liquefied natural gas (LNG) to be transported by rail in specialized tank cars, starting 31 October 2023. This final rule overturns a Trump-era rule that allowed for the bulk transport of LNG by rail. The USDOT took these actions through the Pipeline and Hazardous Materials Safety Administration (PHMSA) and the Federal Railroad Administration (FRA).
For decades, LNG and cryogenic liquids similar to LNG have been transported by highway and rail respectively within the United States. However, the Hazardous Materials Regulations (HMR) did not authorize the bulk transport of LNG in rail tank cars, except by special permit.
On 24 October 2019, PHMSA, in coordination with FRA, published the Hazardous Materials: Liquefied Natural Gas by Rail Notice of Proposed Rulemaking (NPRM) in the Federal Register. The NPRM updated the HMR to allow for the bulk transport of LNG by rail and it is consistent with Executive Order 13868.
The suspension of this final rule comes amid a legal challenge from a group composed of 14 states (California, Delaware, Illinois, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington) and the District of Columbia, and another group composed of six environmental organizations (Sierra Club, Center For Biological Diversity, Clean Air Council, Delaware Riverkeeper Network, Environmental Confederation of Southwest Florida, and Mountain Watershed Association). In parallel, the Puyallup Tribe of Indians petitioned for review of the rule in the US Court of Appeals for the Ninth Circuit; the Tribe also filed an administrative appeal of the final rule before PHMSA.
In addition to the suspension of this rule, one company that had received a special permit in 2019 to ship LNG by rail, had their permit extension request denied by Secretary Buttigieg in April 2023.
