In the summer of 2002 passenger services resumed after a break of seventy-two years, initially diesel-hauled.
The railway built a new steam locomotive, to a design based on the Kerr Stuart No.4, which arrived on the railway on 17 May 2005 and runs as No.7 (the Corris Railway never officially named its locomotives).
No.
7 went into service on 20 August 2005, fifty-seven years to the day since the last train on the original railway, and now hauls the regular passenger service between Corris and Maespoeth.

The railway is also actively pursuing a southwards extension towards Machynlleth, with the initial aim of extending the line to Tan-y-Coed, midway between Esgairgeiliog and Llwyngwern and some two and a half miles south of Corris.
As always, this is involving lengthy negotiations with the authorities, not least due to the line south of Maespoeth running immediately adjacent to the A487 trunk road.
While these are continuing the railway has consolidated its facilities at Maespoeth with the construction of a new two-road carriage shed in the adjacent field (the original carriage sheds at Corris and Machynlleth having been demolished).
In 2015 work began on building the new diversion embankment to enable the southerly extension.

During 2009 the railway marked the 150th anniversary of the first train on the Corris with a series of events, including demonstration horse-worked freight trains and gravity runs of rakes of waggons.

The revived Corris Railway has maintained friendly links with the Talyllyn Railway, which resulted in both of the original Corris locos and rolling stock returning to the railway.
In 1996 ex-Corris loco No.
4 returned to celebrate its 75th anniversary.
In 2003 ex-Corris loco No.
3 returned on the occasion of its 125th anniversary with a heritage train of coach No 17, brake van No.
6 and two trucks.
Corris No.
5 visited the Talyllyn Railway in 1983 and 1990, and No.
7 in October 2011.
It hauled a few charter trains and played a part in the TR's Corris Weekend, when it ran with the two surviving ex Corris engines; No.
4 (Edward Thomas) and No.
3 (Sir Haydn) and stock.

Both the surviving original locomotives have visited the Corris since its reopening.
In 2012 No.
3 featured in a steam Gala over May Bank Holiday weekend along with the railway's resident steam loco No.
7.

No.
3's boiler ticket expired on 17 May 2012 and the loco was on static display at Maespoeth until February 2013 when the loco left the Corris to tour heritage railways and museums in the UK to raise awareness of the Talyllyn and to raise funds for its overhaul.
