Even without leading scorer Keiffer Putman's 15 points a night, Sparks found plenty of offensive options as four players finished in double figures.
Bobby Brown led the way with 14 points on 6-of-11 shooting. Both Mike Albior and Geo Vasquez added 11 points, while Jessie Ray chipped in 10. Albior also dished out nine assists. Vasquez made all five of his field-goal attempts and was one rebound from a double-double.
The game was still close after the first quarter with the visitors leading 17-11, but the Maroon and Gold out scored North Tahoe 14-6 in the second quarter to take a 31-17 lead at the intermission.
The Railroaders piled it on by putting up 16 points in the fourth while allowing only six.
Sparks (11-8, 5-2) takes on South Tahoe at home Friday. Tip-off is scheduled for 7:30 p.m.
