Maritime Line trains start from Truro railway station, usually originating from the bay platform, at the left side of the main platform beyond the footbridge.
The trains join the main line for the first half-mile to Penwithers Junction, passing through the 70-yard (64 m)-long Higher Town Tunnel on the way.
At this point the line to Penzance curves away to the right; the line to Falmouth was originally the Cornwall Railway main line and so runs straight ahead while the Penzance line was built by the West Cornwall Railway Company.
The Maritime Line today only has a junction with the westbound (down) line; trains running towards Truro (the up direction) come inbound on the down main line, the same line used by trains departing Truro for Penzance.
The line from Penwithers to Falmouth Docks is single track, with the exception of the passing loop at Penryn.

From the tunnel the line emerges into the countryside outside Truro.
The small excavated area of land on the left is a Local Nature Reserve which supports rare plants due to its unusual position in a triangle of rail routes - the Maritime Line, the disused continuation of the West Cornwall Railway to the riverside at Newham, and a never-built route allowing Cornwall Railway trains to reach Newham.
The route to Newham is now a cycle path round the edge of the city.

One and a half miles from the junction, the line enters Sparnick Tunnel, which is a little over a quarter of a mile long.
Although the line has only ever had a single track, most of the engineering, including the tunnels, was designed to carry a second one.

The line, which heads south-westwards until this point, now heads towards the south and passes high above the silted-up Restronguet Creek on Carnon viaduct.
This valley was the route of the Redruth and Chasewater Railway down to quays at Devoran, about a mile beyond the viaduct.
It is now part of the Mineral Tramway Trails.

A half-mile later, the line comes to Perranwell railway station, nearly four miles from Truro.
A modern shelter is situated on the platform, built in a style inspired by older railway buildings.
As with all stations except for Truro, the platform is on the left as the train travels towards Falmouth.
In the forecourt is the old Cornwall Railway goods shed.

The line now begins to head west, passing over the short Perran Viaduct and then south again along the hillside above Perranwell village before passing through the 374-yard (342 m)-long Perran Tunnel.

Turning south-eastwards, the line now passes over Ponsanooth Viaduct, the tallest on the line.
Ponsanooth village is on the hillside to the right, while the River Kennal runs below to join up with Restronguet Creek.

The line passes beneath the A39 road from Truro to Falmouth at Treluswell, Four Cross, and then shortly enters Penryn which grew up at the head of a large inlet of the River Fal.
Penryn railway station is at the top of the town, and we have views across the town to St Gluvias on the other side of the harbour.
The station is eight and a quarter miles from Truro, and the platform shelter is identical to the one at Perranwell.
Beyond the station the line passes over the Collegewood Viaduct.
The last timber railway viaduct in Cornwall was here, but was replaced by this stone structure on 22 July 1934.

At Penryn there is a wide open space now occupied by student housing for the Tremough Campus of the University of Falmouth.
This was the goods yard where wagons were loaded and unloaded.
There is also another platform visible on the other side of the train, though it is overgrown.

The line soon enters the outskirts of Falmouth.
The town was established at the entrance to the inlet that leads to Penryn; it has now nearly spread to reach that town.
Trains first call at the Penmere railway station, useful for people heading for the top of The Moor in the town centre, or for the newer western suburbs.

Passengers get a quick glimpse on their right of Falmouth Bay before trains call at the concrete platform of Falmouth Town railway station, which is nearer the National Maritime Museum, the wate
