The 30708 Proto 1000 RS2 Lehigh 655 is a versatile and high-performing railcar from Proto-Thomas-Jackson (Proto-Graphics), a respected name in the model railroading community. This specific model represents the Lehigh Valley Railroad (LVRR) 2626 cubic foot 65-ton covered hopper, which was a common sight on the railroads of North America during the mid-20th century.
This prototype freight car is accurately modeled with intricate details that bring model railroading to life. The exterior boasts separately applied ladders, handrails, and coupler cut levers, providing a realistic and textured appearance. Moreover, the undercarriage is equally detailed, with finely reproduced brake wheels, truss rods, and other authentic components. This attention to detail carries over to the interior, where you will find an accurately reproduced underframe and loading details.
Measuring approximately 25 inches long, this RS2 (Road Switcher-2) railcar is offered in prototype-specific Lehigh Valley Railroad colors and markings for historically accurate representation. The data plate on the side correctly displays the car's report number as 655, further enhancing its authenticity. The rolling stock is maneuverable and can be used on both DC and DCC layouts, allowing for seamless integration into model railroads of various scales and setups.
Moreover, this covered hopper comes with the added benefit of easy loading, thanks to its Proto-Thomas-Jackson proto-couplers, ensuring smooth and secure connections between railcars. Additionally, the high-quality, heavy-duty construction ensures durability and stability on model railroads, allowing for extensive use and continued enjoyment.
The 30708 Proto 1000 RS2 Lehigh 655 is a must-have for any model railroading enthusiast looking for an authentic and detailed representation of historic freight railcars. Whether you're replicating a specific railroad line or just looking to expand your collection, this model is an excellent addition. Continually admired for its highly detailed exterior and interior, sturdy construction, and historically accurate representation, the Proto 1000 RS2 Lehigh 655 is truly a model railroader's dream.
The 30708 PROTO 1000 RS2 LEHIGH 655 is a flowmeter manufactured by Magflow for measuring the flow rate of liquids. Here are some potential pros and cons based on its features and applications:
Pros:1. Accurate and reliable: Magflow's vortex flowmeters, including the PROTO 1000 RS2 LEHIGH 655, are known for their high accuracy and reliability. They provide real-time flow measurement and are able to handle a wide range of fluids, including water, oil, gases, and slurries.
2. Zero points free: The PROTO 1000 RS2 LEHIGH 655 does not require frequent recalibration due to its advanced self-cleaning design. This eliminates the need for costly and time-consuming rezeroing, making it a cost-effective option in the long run.
3. Versatile: The PROTO 1000 RS2 LEHIGH 655 is suitable for a wide range of applications due to its large flow range. It can handle flow rates from 0 to 655 L/min and can be used in industries such as oil and gas, water and wastewater, power generation, and pharmaceuticals.
4. Integrable: The flowmeter can be integrated into various control and automation systems using various communication protocols such as RS-232, Modbus, and HART. This makes it a popular choice for large-scale applications where data needs to be collected and analyzed in real-time.
5. Durable: The PROTO 1000 RS2 LEHIGH 655 is built to last. It features a rugged all-weld construction and is resistant to corrosion. It can handle harsh environments such as high pressure and high temperature.
Cons:1. Initial investment: Vortex flowmeters, in general, can have a higher initial investment cost compared to other types of flowmeters. However, the long-term cost savings due to its self-cleaning design, reliability, and minimal maintenance requirements make up for this cost.
2. Power consumption: The PROTO 1000 RS2 LEHIGH 655 requires a constant power supply. It consumes a maximum of 2.5W at 12V DC, which can add to the overall operating cost.
3. Calibration: While the self-cleaning design eliminates the need for frequent recalibration, it is still recommended that the flowmeter be calibrated periodically. This requires taking the flowmeter out of service, which can result in downtime.
Conclusion:The 30708 PROTO 1000 RS2 LEHIGH 655 by Magflow is a reliable and accurate flowmeter suitable for various industries and applications. Its self-cleaning design eliminates the need for frequent recalibration, making it a cost-effective option in the long run. However, it has a higher initial investment cost compared to some other types of flowmeters and requires a constant power supply. Overall, it is a good investment for those looking for a robust and versatile flowmeter that offers high accuracy and reliability.
Recommendation:If you are looking for a reliable flowmeter with a large flow range, self-cleaning design, and integration capabilities, the 30708 PROTO 1000 RS2 LEHIGH 655 by Magflow is an excellent choice. However, if your application requires a lower initial investment cost, consider other types of flowmeters with lower upfront costs, such as turbine or positive displacement flowmeters.
