What is the definition of rolling stock?
Rolling stock is defined in the Buy America regulations (49 CFR Part 661.3) as: "transit vehicles such as buses, vans, cars, railcars, locomotives, trolley cars and buses, and ferry boats, as well as vehicles used for support services.". Where can I find the definition for "Rolling Stock"?
How to control the working time of rolling stock drivers?
Meanwhile, it is better that rolling stocks complete their depot deadhead exiting and entering operations as quickly as possible to control the non-productive working time of drivers. Reducing total depot deadhead (exiting and entering) running times is usually another objective.
What is rolling stock under the Buy America Act?
Rolling stock is defined in the Buy America regulations (49 CFR Part 661.3) as: "transit vehicles such as buses, vans, cars, railcars, locomotives, trolley cars and buses, and ferry boats, as well as vehicles used for support services." (Posted: December, 2010) Is rail for fixed guide-way considered rolling stock?
Can two rolling stocks be turned back at the same station?
The rolling stocks from both the upstream and downstream can be turned back at this station, while two rolling stocks from different directions are not allowed to turn back at the station simultaneously.
What is rolling stock in transportation?
Rolling stock is defined in the Buy America regulations (49 CFR Part 661.3) as: "transit vehicles such as buses, vans, cars, railcars, locomotives, trolley cars and buses, and ferry boats, as well as vehicles used for support services." (
What is the meaning of rolling stock in a railway?
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, freight and passenger cars (or coaches), and non-revenue cars.
What is the importance of rolling stock?
Strengthening competitiveness. Another important factor in strengthening competitiveness is to optimise the capacity utilisation of rolling stock. This yields a lower unit cost and reduces the absolute capacity need.
What is rolling stock maintenance?
Rolling stock is the most maintenance intensive part of the railway system and is the most vulnerable if maintenance is neglected. A stalled train will block a railway immediately and will reduce a timetable on an intensively used system to an unmanageable shambles for the remainder of the day.
What is a rolling stock condition assessment?
The Real-Time Transit Infrastructure and Rolling Stock Condition Assessment program funds cooperative agreements to engage in demonstrations to assess and identify infrastructure deficiencies in public transportation rolling stock via innovative technologies to keep public transit assets in a state of good repair.
How much is the FTA 2020?
What's New. On November 30, 2020, FTA announced $1.37 million in competitive grant funds to six projects in six states for the Real-Time Transit Infrastructure and Rolling Stock Condition Assessment Demonstration Program to support infrastructure innovation and safety in the transit industry.

Make Sure Your Paperwork is in Order
This one seems like a given, but something so simple can have a dramatic impact on how smoothly your product’s transit goes. Making sure you have all your paperwork ready and in order can help you avoid costly holds at customs when importing.
Rethink Distribution Centers
Distribution centers are far more than just another stop in your supply chain. They can easily become a great way to lose time and money. However, most supply chains rely heavily on them. Take the time to evaluate how your distribution centers work for your supply chain.
Book Full Containers
If you’ve got enough product to fill a full container, you can save yourself time, money, and stress by avoiding shipping partial containers or truckloads.
Plan for Transit Time
When shipping internationally, having your lead times planned out is imperative. Most sailing schedules only have ships leaving port 1-2 times a week, with specific cutoffs for when your cargo must be loaded before departure.
Utilize Available Technology
Everything that’s been covered so far is made far easier with good technology. If you have visibility technology available to you, make sure you use it to its fullest. If you don’t, it may be time to investigate what options might be best for your supply chain and your budget.
Abstract
This paper investigates an integrated rolling stock deadhead routing and timetabling problem from the rolling stock scheduling in a complicated urban rail transit line.
1. Introduction
Public transport has become an important means of daily urban transportation since the very beginning of urbanization.
2. Problem description
Without loss of generality, we focus on the IRSDRT problem in a complicated URT line (with multiple depots and turn-back stations, multiple line services, and multiple rolling stock compositions) under the Chinese case.
3. Problem redefinition and network construction
An intuitive method to solve the IRSDRT problem is to extend the most related model, proposed by Wang et al. (2019) for a similar problem in a short time period, by considering both the depot deadhead exiting and entering operations in an operation day.
4. Model formulation
In this section, we formulate the studied IRSDRT problem as IM, based on the generalized set partitioning type problem redefinition presented in Section 3.1. The main notations used in our models (IM, AM, and RIM) are formally defined in Tables 1 and 2.
5. Solution method
In linear and integer programming, two efficient decomposition algorithms, row generation and column generation, are widely used to deal with large-scale problems ( Wolsey, 1998 ).
6. Computational experiments
In this section, a set of hypothetical instances (constructed based on the hypothetical URT line shown in Fig. 2 ), a set of practical-size realistic instances, and a large real-world instance (constructed and collected from the Chongqing rail transit line 3 in China) are used to assess the potential of our approaches.
