The GE Dash 7 series is a line of locomotives that has been around since the 1970s. It was designed to be a reliable and efficient option for railroads.

The Dash 7 series was built with a focus on safety, and it features a number of innovative safety features. These include a crash energy management system and a advanced braking system.

One of the key benefits of the Dash 7 series is its ability to operate in a variety of conditions. It can handle high speeds, steep grades, and extreme temperatures.

Data Sheet & Specifications

The GE Dash 7 is a series of diesel-electric locomotives that have been in operation since the late 1970s. The C30-7 model was produced from 1976 to 1986, with a total of 1,078 units built.

The C30-7A model was a variant of the C30-7, with only 50 units produced in 1984. Both models have a similar length of 67' 3".

The GE Dash 7 is powered by a 7FDL-16 or 7FDL-12 engine, depending on the model. The C30-7 model has a 7FDL-16 engine, producing 3,000 horsepower, while the C30-7A model has a 7FDL-12 engine, also producing 3,000 horsepower.

Here are the specifications for the C30-7 and C30-7A models:

The C36-7 model, which was entered into production in June 1978, has a similar length of 67' 3". It is powered by a 7FDL16 engine, producing 3,600-3,750 horsepower.

Common Features

The GE Dash 7 Series is known for its consistency across models, and one of the key common features is the AAR wheel arrangement, which is a B-B configuration. This design provides stability and balance.

One of the prime movers used in these models is the GE 12-cylinder V-type 7FDL12 diesel engine, which is a four-stroke engine.

Models

The GE Dash 7 series offers several models to choose from, each with its own unique features.

The six axle models are a great option for those who need a reliable and powerful locomotive. They feature an AAR wheel arrangement of C-C, which provides excellent stability and maneuverability.

The prime mover in these models is a GE 12-cylinder V-type 7FDL12 or 16-cylinder V-type 7FDL16 four stroke diesel engine. This provides a significant amount of power and efficiency, making them well-suited for heavy hauling tasks.

B23

The B23 is a model of locomotive that's worth taking a closer look at. It replaced GE's U23B and competed with the successful EMD GP38-2.

A total of 537 B23-7s were built, making it a significant model in its time. These engines were sold to 11 different customers in the US and Mexico.

The Southern Railway's 54 units had a unique feature - Southern's "standard" high-short-hoods. This is a notable detail that sets them apart from other B23-7s.

These engines are often rebuilt into Control Car Remote Control Locomotives (CCRCL) due to their low value on the used locomotive market. This is likely due to their age and the fact that they're no longer in high demand.

The B23-7 has a power output of 2,250 hp (1,680 kW), making it a capable model for its time.

B30

The B30 model is a significant part of the locomotive family, and it's worth taking a closer look at its specs. The B30-7 was built for U.S. customers, and it's a notable upgrade from its predecessor, the U30B model.

The B30-7 was equipped with a powerful 16-cylinder 7FDL16 engine, which provided a significant boost in power output. This engine produced 3,000 horsepower.

The B30-7 was produced between December 1977 and May 1982, with a total of 279 units manufactured during that time. These production numbers include the three different B30-7A variants.

C30

The C30 model is a significant one in the world of railroads. It was manufactured between 1976 and 1986.

The C30-7 model, a variant of the C30, was specifically produced during this time period. It was fitted with a 16-cylinder 7FDL engine.

A total of 1,137 C30-7s were built, all of them for North American railroads. These production numbers include the 50 C30-7A variants.

Approximately half of the C30-7s have since been exported to Brazil.

The C30-7A was a variant of the C30-7 fitted with a 12-cylinder 7FDL12 engine generating the same power output as the B30-7.

This engine used less fuel than the 16-cylinder version.

A total of 50 C30-7As were built in mid-1984, and delivered to Conrail.

They are externally similar to the C30-7, except that they have six tall hood doors per side (in place of eight) and moved front grilles on long hood, also only 4 steps.

In 2003, nineteen C30-7As were rebuilt and exported to Estonia as C30-7Ais.

The C30-7A consumed less fuel and generated less noise and emissions than its 16-cylinder counterpart.

Conrail ordered 50 units, making it the exclusive domestic customer for this model.

GE Brazil continued to construct a variant of the model as late as 1990.

A New Model

The concept of a new model is based on the idea of a paradigm shift, where a new way of thinking is introduced to replace an old one. This is a key aspect of the evolution of models.

In the context of models, a new model is often a response to the limitations of existing models. For example, the limitations of the old model led to the development of a new model that incorporates more variables.

The new model is designed to be more accurate and efficient than the old one. It takes into account new data and insights that were not available before.

One of the key features of the new model is its ability to handle complex systems. This is made possible by the use of advanced algorithms and machine learning techniques.

The new model is not a replacement for the old one, but rather a complement to it. It provides a more nuanced understanding of the system being modeled.

The adoption of the new model has been gradual, with many organizations still using the old model. However, as the benefits of the new model become more apparent, its use is becoming more widespread.
