The best photo spots for trainspotters in Rhein-Sieg-Kreis

1) Siegburg/Bonn – ICE hub with high-speed feel

The Siegburg/Bonn station sits directly on the Cologne–Frankfurt new-build line (NBS). ICE trains race past or stop here at a dense frequency – ideal for dynamic subjects and modern vehicle series.

• Highlights: ICE 3, ICE 4, Velaro D, plus S-Bahn (including S12/S19) and regional traffic. Architecturally interesting perspectives on the walkways and the station forecourt.
• Best times: Light on southbound trains in the morning, on trains towards Cologne in the afternoon. Golden hour delivers soft contrasts on glass and steel surfaces.
• Positions: Platform ends (observing safety lines), footbridges and publicly accessible areas at the forecourt. Always observe signage and announcements.
• Getting there: ICE, RE and S-Bahn stops. Park-and-ride in the area.

2) Troisdorf – a junction with freight traffic and variety

Troisdorf connects the Sieg line with the axis to Cologne Hauptbahnhof and offers interesting sightlines near the station. Due to the proximity of industrial connections, freight traffic can be observed regularly here.

• Highlights: A colourful mix of container, tank, automotive and steel trains, plus S-Bahn and regional traffic.
• Spots: Platform areas with long views, crossings/bridges nearby (use public areas only) and open-line sections with a safe distance.
• Light: Depends on the direction of travel; line sections offer options in both morning and afternoon. Cloud cover helps avoid harsh shadows.

3) Hennef (Sieg) – Sieg romance with S-Bahn and RE traffic

Hennef sits picturesquely on the Sieg line. Here you’ll find subjects with a river, bridges and plenty of greenery – ideal for classic railway photography.

• Traffic: S-Bahn lines (e.g. S12/S19) and the Rhein-Sieg-Express (RE). Occasionally special workings, especially during diversions.
• Spots: Publicly accessible paths along the Sieg with a view of the tracks, platform areas, bridges with sufficient distance.
• Tips: After rainy spells, morning mist can create atmospheric scenes.

4) Eitorf & Au (Sieg) – wide curves and long sightlines

Towards Eitorf and on to Au (Sieg), wide curve radii and longer sightlines open up. Ideal for staging trains with plenty of surroundings.

• Choice of subject: Wide-angle for landscape + train, or telephoto for shimmering compression on long straights.
• When: Early morning and late light work well – depending on the direction of travel and vegetation.

5) Königswinter & Bad Honnef – a grand backdrop on the right-bank Rhine line

Along the Rhine, Königswinter, Niederdollendorf and Bad Honnef (Rhein) offer impressive combinations of river, mountains and railway. The right-bank Rhine line is known for dense freight traffic and atmospheric long views – heading upstream it flows into the Mittelrhein valley near Boppard.

• Traffic: Regional trains (including RB) and many freight trains with containers, tank wagons, bulk goods and mixed freight.
• Spots: Riverside promenades, bridges and elevated positions with a view of the tracks and water (use public land only, no proximity to the tracks!).
• Light: Afternoon/evening light for trains heading upstream; morning for downstream – depending on the location.

6) Sankt Augustin area (including Menden/Mülldorf) – open views of the Sieg line

In the Sankt Augustin area you’ll find open sightlines onto the line towards Hennef/Siegburg. Practical for everyday sightings with plenty of scheduled traffic.

• Traffic: S-Bahn, regional traffic, occasional diversions.
