Delivery of switches and rails for track reconstruction and stop in Naumburger Straße in Jena.
Delivery includes:
• two turnouts (W16 and W 17) EW 60R1-50-1:10-R,
• approx. 120 m straight grooved rails 60R1,
• approx. 310 m curved grooved rails 60R1,
• approx. 70 m straight grooved rails 55R1,
• approx. 520 m curved grooved rails 55R1,
• approx. 850 m straight vignole rails 49E1,
• approx. 780 m curved vignole rails 49E1,
• 4 straight transition rails 60R1/49E1 with lengths L = 12,000 mm
• 4 straight transition rails 60R1/49E1 with lengths L = 7,500 mm
In addition to the preparation of the corresponding plans and drawings, installation supervision is part of the tendered delivery. These services are remunerated with the corresponding lump sums.
The scope of supply includes the transport of all systems and rails up to the installation location including unloading. The hoist is provided by the track construction company. All expenses that are necessary for transport to the installation site must be included in the unit prices. The transport as well as the delivery dates are to be coordinated with the client and the track construction company.
All rails in the turnouts shall be designed as grooved rails, profile 60R1, with grade 290 GHT-CL or equivalent. This material can be welded on without significant preheating like steel grade R220G1, but has a wear behavior at least like R260 or better. The supplier must prove his material concept by means of test internals/reference installations, in particular the better wear behaviour compared to rails in the material R200 or R220G1. Welding recommendations and examples must be provided by the supplier.
To minimise the installation time, the points must be delivered completely welded.
The points are to be delivered bolted to hardwood sleepers of size 1. The sleepers and the fastening material for the turnouts are included in the scope of delivery.
The two turnouts are to be supplied with built-in and completely operational changeover systems as well as the point heaters (chamber heating with protective box, protective tube and heating element with plug-in connection).
The entire systems are to be constructed with stray current insulation.
In order to minimise installation risks, all turnouts must be completely designed by the manufacturer.
The rail joints shall be designed with a 0 mm joint gap. Technologically induced shock gaps, in the case of construction site welding impacts, must be fed by spacers. The impact gaps must be documented by grain strokes (distance 1.00 m).
The rails shall be supplied in the appropriate track radii and in different lengths. Rail junction boxes, track drainage boxes, insulated terminals, ribbed plates, etc. and sleeper constructions are not part of this delivery. The installation is carried out by the track construction company.
All systems are to be manufactured in operating system S for trams with 1000 mm gauge (measuring level 10 mm below GFT).
In principle, the VDV guidelines and additional guidelines apply in the latest version.
The turnouts, crossings and tongue devices must be manufactured taking into account the TL, SpR and VDV guidelines.
Safe and low-wear lane guidance must be ensured within the framework of the Lane Guidance Guidelines (SpR) and their supplementation, taking into account the relevant vehicle data, which will be provided by the client if required.
In order to minimize welding, the two transition rails of the out-of-town track must be manufactured together with the W17 switch. Welding between stations 0+028,612 and 0+031,612 is not permitted. This also applies to technological welding.
