In the north east corner of the gardens is the gauge Exbury Steam Railway that goes on a journey through a tunnel, around Dragonfly Pond, through the Summer Lane Garden, along the top of the rock gardens and into the American Garden. The railway was built in 2000–2001 as an additional attraction in the gardens. Two narrow-gauge-style
0-6-2 tender tank locos were built specially for the line by the
Exmoor Steam Railway. The railway is a member of
Britain's Great Little Railways. The railway proved to be more popular than anyone had anticipated, with trains often needing to be double-headed. To solve this problem, a much larger
2-6-2 tender loco, called
Marriloo, was built at Exmoor, and entered service in 2008. It is notable for having carried
Elizabeth II on a footplate trip round the railway. The railway stages popular Ghost Trains during the October half-term and Santa Steam Specials in the run-up to Christmas. A diesel locomotive called
Eddy is used for shunting operations. ==References==
