LEGO® City Trains - Flexible Tracks (7499) is rated 3.0 out of 5 by 101.
Rated 4 out of 5 by from Flex Track Best Practices I took the challenge of effectively employing flex track in my layouts and derived a set of principles for improved play experience. Using flex track can offer a degree of granular control not previously available. I would recommend snatching up a few of these while they are still in production. 1.) Use flex tracks as spacers: When using this technique, I lock one flex track element into the straight position using a 2x4 dark stone gray tile placed in the center of the flex track. This prevents the layout from changing shape as the train passes over. curve radius 1: curve track only curve radius 2: 1 curve track 1 spacer (repeat) curve radius 3: 1 curve track 2 spacers (repeat) curve radius 4: 1 curve track 3 spacers (repeat) While other radii can be achieved, the various configurations above hug each other nicely and create aesthetic appeal. 2.) Use only one or two conjoined flex tracks when not locked into position. I only use flex track to make very fine angle adjustments in my layout. For example, to offer a minimal amount of leeway in my angle, I may place one flex track at each end of a long straight configuration in order to achieve a gentle and elegant slope, or to make a minor correction here and there. 3.) Due to the loss of traction when passing over flex track, I can leverage a series of flex track locked into a straight position to slow a train prior to entering a curve in order to prevent derailing. This is a helpful effect to prevent inexperienced locomotive engineers from launching the train at full speed around curves, or anywhere that deceleration is desired; for instance, near a train station. 4.) Add a spacer during elevation. Due to the change in angle when a track climbs in elevation, the situation may require an alteration of track length to accommodate the trigonometric effect. A single flex track used as a spacer is often helpful in this circumstance. While somewhat awkward, I recommend trying to incorporate the flex track into your layouts and leveraging the unique characteristics of this piece. I own hundreds of them and employ them regularly with delight. Learn the subtle nuances of this piece and gain a new twist on LEGO track layouts. Regarding straight tracks, these elements are so useful, that they should be offered in sets of straight track only (maybe x20). Additionally these should be sold individually in the pick a brick store.

Rated 1 out of 5 by from Unhappy with train tracks I've recently purchased several of the train kits. However, the options for buying track are extremely limited. I wish that Lego offered packs of specific kinds of track (straight, curved, switch, flexi), but all that's available are these combo packs. Additionally, PAB does not carry train track. Please, Lego, support your train builders.

Rated 1 out of 5 by from poor design, insufficient pieces The design of the flexi tracks is pretty poor and makes derailment a common thing. The fact that this set is also not a complete oval is pretty disappointing too. It would require 4 of these sets to make a loop.

Rated 3 out of 5 by from straight track! I like the idea of the flexible track; it can be used to fill some spaces and angles that would otherwise be difficult. Also, you may use it as either straight or curved track, but it's too much! If it were 10 straight tracks instead of eight and 8 flexible tracks instead of 16, it would be more than enough for collector and, probably cheaper for LEGO! The flexible track makes your trains to lose traction and deviate. If you use full loops and disperse the flexible track, the problem gets smaller but it is still there!

Rated 1 out of 5 by from Tracks type should be sold separately I am not a fan of flexitracks at all. And customers should have the option to purchase straight tracks only. Same with curves and flexitracks.

Rated 1 out of 5 by from We need straight track only! I must rate this as one star as it contains those flex tracks. While there is nothing wrong with that track in itself, we have TONS of it and really need more straight track. I resent having to get more flex track just to have more straight track. This is an issue that has been going on for years. One would think that Lego would give better customer support than this! Very disappointed in Lego!
