N - HO: SNCF TGV Atlantique - Bridges and pillars (Poitiers)

( French text at the end )

Photos taken during a personal trip.

The walls of this bridge have ripples that remind us that many high-speed trains in the Atlantic network are destined for the sea.

To have a more technical analysis of these pictures, I asked an old colleague, son of railwayman. He pointed at the "CAB" signs and the 15kv catenary. For him, it would be a TGV section that would link the conventional network supplied in 15 kv and the LGV (high-speed line) which would be in 25kv. An hypothesis that makes sense: the work in question is in urban environment: avenue de Paris at POITIERS.

About the STL files available to you:

• All files were designed for HO. To get the N compatible files, you need to print them at 55%.

• Unless you have a high-performance printer, select N for untextured files

• Best printing results are obtained by printing bridge decks standing. Place the top of the various sections of the bridge stack in with the printing table. Their bottom part in N is very fragile and requires a certain precision of printing

• Slight slope for the bridge may be considered; pillar sections of different heights are available. Once the decks are assembled, the upper part of the bridge piles has been designed to receive, if necessary, glue in quantity

• If necessary, ages for threaded rods of 5 mn in HO and 3 mn in N are provided

• Not having HO equipment, tests were conducted exclusively in N. The track crossings are designed for N rails, Fleischman Piccolo

• If you have any particular issues, please me for possible improvements

Photos taken during a personal trip.

The walls of this bridge bear ripples that remind us that many of the Atlantic network's TGV trains are destined for the sea.

For a more technical analysis of these shots, I asked a former colleague of mine, the son of a railway worker. He pointed out the "CAB" signs ("circulation dirigée vers une ligne à signalisation de cabine") and the 15kv catenary. In his view, this would be a TGV section linking the conventional 15kv network with the 25kv LGV (Ligne à Grande Vitesse). A hypothesis that makes perfect sense: the structure in question is in an urban environment: avenue de Paris in POITIERS.

About the STL files available to you:

• All files have been designed for HO. To obtain N-compatible files, they must be printed at 55%.

• Unless you have a high-performance printer, choose non-textured files in N.

• The best printing results are obtained by printing the bridge decks upright. Place the upper part of the various bridge pier sections in with the printing table. Their N-shaped lower sections are very fragile and require a certain printing precision.

• A slight slope can be envisaged for the bridge: pillar sections of different heights are available. Once the decks have been assembled, the upper part of the bridge piers has been designed to receive, if necessary, glue in quantity

• If necessary, ages are provided for 5-minute threaded rods in HO and 3-minute threaded rods in N

• As we had no equipment in HO, the tests were carried out exclusively in N. The track crossings are designed for Fleischman Piccolo N rails.

• If you encounter any particular problems, please do not hesitate to me for possible improvements.
