I thought so but wasn't certain. But that's why IBX is using 14' centers instead of something narrower (plus it's an old ROW so no need to squeeze)

TCRP 155 calls for 14’ when placing catenary poles between ballasted tracks, which the typical section is calling for
![TCRP 155
2.3.3.3 Vehicle Clearance to Wayside Obstructions and Other Tracks
It is not unusual to have clearance restrictions on an LRT line that cannot be either simply or economically altered. In such cases, the track designer should coordinate with the vehicle and structural designers to ensure that the vehicle dynamic envelope considers these limitations so that adequate clearances result. Vehicle dynamics are governed by the car's suspension systems) and, therefore, indirectly by numerous factors of track and vehicle interaction. For multiple-track situations, multiple clearance envelopes must be considered. Overlapping of the vehicle dynamic envelopes from adjacent tracks obviously must be avoided. The resulting requirements will dictate minimum track centers and running clearances for tangent and curved track, including construction and maintenance tolerances as input to the track alignment calculations.
In general, the absolute minimum tangent track centers for vehicles of normal width (e.g., 2650 mm / 8.7 feet) for rigid trackforms (direct fixation or embedded) are 13 feet 6 inches [about 4.15
m] with a catenary pole between the tracks. If the poles are outboard of the tracks, 11 feet [about 3.35 m] is the typical minimum spacing. Tangent track center spacing for ballasted track is typically 6 inches [15 cm] greater than those for rigid trackform track due to greater allowances for construction tolerances and shifting of the tracks over time. Track curvature and superelevation increase these dimensions. These issues are discussed further in Chapter 3, Article 3.8.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:khnoilewj2micgy5pk3dqksf/bafkreihthluaiawv7giavatumgiikdwqftmgdgdg2o3exywcjfafhkdxc4@jpeg)

Top speed is the same, but they don’t have to slow as much in curves because the tilting counteracts some amount of cant deficiency

Seeing this post this morning helped convince me to commit to my goal of 2 climbs today instead of cutting my ride after the first, thank you for the boost

Homegrown is fuckin best. Can walk from the Inman Park/Reynoldstown MARTA station, or can catch the 21 bus from the Five Points station
