The Mark VI design is versatile. It can be configured in various gauge widths (914 mm to 1676 mm) and in single axle, bogie, or combination configurations as required to meet a specific railway's axle loading and curve radius requirements. Dual cabin and coupler configurations are also optionally available.

High-speed track travel characteristics help accommodate job requirements dictated by short track maintenance windows.

Jupiter Control System uses remote I/O (Input-Output) devices to simplify railway maintenance equipment's electrical control systems.

Advanced System V control system delivers accurate, repeatable results and effective operator interface for computer-controlled automatic ramping, super elevation, zeroing of references, and continuous cross level monitoring.

Easy to use control system software monitors each circuit status "behind the scenes" and reports errors when they occur

CAD/CAM and Finite Element Computer Analysis design, extensive testing, and use of proven workhead and reference system designs assure component integrity.

The Mark VI Tamper is a new generation machine for high quality production and switch tamping. In today's world - productivity, safety, ease of use and maintenance and durability are key factors in the purchase of new equipment. Harsco Rail has built this new generation tamper with these factors in mind.

For example, to accomplish high productivity, the Mark VI reduces travel time to the work site with travel speeds up to 80 km/h (50 mph). It utilizes short work windows with a quick deployment reference system.

A spacious sound-suppressed (78 dba) and climatized cab and "user friendly" computer controls make the operator's environment more comfortable, reducing fatigue, while excellent visibility of the work area and the track ahead enhance safe operation.

A computer-based control system provides automatic ramping, automatic superelevation, continuous crosslevel monitoring and automatic zeroing of references. The optional Line Lite Lining System can line through curves without pre-plotting, or provide "best fit" of curves with the ability to easily adjust the fits. Use the curve data from an analyzer car, and print out curve data and graphs.

Troubleshooting is faster and made easier by computer-based diagnostics. And easy access to the engine pumps, electrical cabinets, and fuel or hydraulic fill ports reduce maintenance time.

While the Mark VI features many new tamping innovations, there's one thing that remains constant-the high quality track behind a Harsco Rail™ machine. Quality that comes from the superior ballast compaction of positive displacement vibrators and uniform tamping depth. Quality that comes from the accuracy of the Delta Reference System.

The Mark VI is durable, to deliver extra value from your investment with a boxed beam frame to resist lifting loads; rugged, proven vibrator assemblies; and easily upgraded control system.

Jupiter 2000 is a distributed I/O system developed by Harsco Rail to meet the demanding control requirements of railway maintenance equipment. Performance superior to commercially available systems was needed in terms of ruggedness, reliability, speed, simplicity and diagnostic capability.

The distributed I/O intelligent control system uses a Control Area Network (CAN) to communicate with modules distributed about the machine. An industrial network cable connects a series of I/O modules strategically positioned around a machine to be in close proximity to the devices with which they interact. Designed for exposure to harsh environmental conditions, these modules are fully potted to provide a high degree of vibration tolerance that allows direct mounting to almost any part of a machine.

The "plug and play" capability of Jupiter allows modules to be exchanged between completely different machines with ease. All devices that connect to the Jupiter 2000 system incorporate connectors to facilitate rapid field replacement. The majority of the cables in the system are identical and vary only in length. Only a few spare cables (equal in length to the longest in actual use) need be carried to make it possible to replace any cable on a machine.

Main or Work Screen Components

The System V main or work screen is composed of several panels, which are updated continuously as the machine is operated. Each panel is devoted to a particular function or group of functions, which are listed below.

System V uses graphic symbols and icons for the vast majority of control and status indicators, thus greatly reducing the need for translation. The human mind is capable of absorbing graphic information (pictures) much more efficiently and quickly than text. Therefore, most displays show pictures or icons of the equipment involved to indicate options and status. Help screens and status are available in any language.

During recording of track, the curvature, crosslevel and surface data is displayed on-screen. Immediately after recording, the curve is automatically best-fit and saved without operator interventions, and displayed for approval. By displaying the throws or slues, the operator knows how far the track will move before beginning work. The operator has complete control, and may, if desired, make changes by the visual method of "rubber banding," where he knows at all times what results will occur. A USB memory device may also be used to automatically accumulate data from the tamper for examination or modification on an office PC or laptop.
