연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A flangeway former for use in association with a rail boot that encases at least a portion of a rail having a rail head and a rail base, comprising: a body having a first side and a second side, wherein said first side comprises a flange that abuts the rail boot at a surface adjacent the rail head on a gauge side of the rail, and a groove that receives a protrusion on the rail boot at a surface adjacent the rail base on a gauge side of the rail, andwherein said second side comprises at least one laterally protruding tab having anchor means and that is at least partially embedded in road bed material on a gauge side of the rail when the flangeway former is installed. 2. The flangeway former of claim 1, wherein the anchoring means is located at a distal end of the at least one tab. 3. The flangeway former of claim 1, wherein the anchoring means is bulbous in shape. 4. The flangeway former of claim 1, further comprising two or more tabs spaced along the second side protruding from the second side. 5. The flangeway former of claim 1, wherein the at least one tab protrudes from a location near the top of the flangeway former. 6. The flangeway former of claim 1, wherein the groove in the first side of the body is used to securely position the flangeway former against the rail boot. 7. An insulated system for an embedded rail comprising: (a) the flangeway former according to claim 1; and(b) a rail boot for use in association with the flangeway former and a rail having a rail head and a rail base comprising: (i) a body comprising a base section that encases the rail base of a rail, a first wall section that encases at least a portion of the rail on a field side, and a second wall section that encases at least a portion of the rail on a gauge side; and(ii) a protrusion on the second wall section adjacent the rail base, which engages a groove on the flangeway former for positioning the flangeway former when the flangeway former abuts the rail boot. 8. The insulated system of claim 7, further comprising: a spacer for use in association with a rail, a rail boot, and a flangeway former comprising: (a) a strip comprising three contiguous channel segments and an arm at each end of the strip, wherein the first and third channel segments are oriented in the same direction and the second channel segment is situated between the first and third channel segments and is oriented in a direction opposite to the first and third channel segments; andwherein the arm at one end of the strip secures the top of the rail boot on a field side of the rail when the spacer is installed; andwherein the arm at the other end of the strip secures the top of the flangeway former on a gauge side of the rail when the spacer is installed. 9. The insulated system according to claim 8, further comprising a rail boot retaining clip system comprising: a first rail boot retaining clip comprising a first section in the general shape of an end of a rail base of a rail that, when employed, forms a rail boot around the field side of the rail base of the rail, anda bracket that is contiguous with the first section but oriented in a direction opposite to the first section,a second rail boot retaining clip comprising a first section in the general shape of an end of a rail base of a rail that, when employed, forms a rail boot around the gauge side of the rail base of the rail, and a bracket that is contiguous with the first section and is configured to attach to a fastener in a manner that holds the rail boot clip tightly against the rail boot, and further comprising an arm extending from an upper portion of the first section to assist in retaining a flangeway former,and a fastener that engages the brackets of the first and second rail boot retaining clips to hold said clips tightly against the rail boot. 10. A flangeway former for use in association with a rail boot that encases at least a portion of a rail having a rail head and a rail base, comprising: (a) a body having a first side and a second side,(b)wherein said first side at least partially abuts the rail boot on a gauge side of the rail, andwherein said second side comprises at least one laterally protruding tab having anchor means located at a distal end of the at least one laterally protruding tab, and wherein the at least one laterally protruding tab is located near the top of the flangeway former and is at least partially embedded in road bed material on a gauge side of the rail when the flangeway former is installed. 11. An insulated system for an embedded rail comprising: (a) a flangeway former according to claim 10; and(b) a rail boot for use in association with the flangeway former and a rail having a rail head and a rail base, comprising: (i) a body comprising a base section that encases the rail base of a rail, a first wall section that encases at least a portion of the rail on a field side, and a second wall section that encases at least a portion of the rail on a gauge side; and(ii) a protrusion on the second wall section adjacent the rail base, which engage a groove on the flangeway former for positioning the flangeway former when the flangeway former abuts the rail boot. 12. A rail boot for use in association with a flangeway former and a rail having a rail head and a rail base, comprising: a body comprising a base section that encases the rail base of a rail, a first wall section that encases at least a portion of the rail on a field side, and a second wall section that encase at least a portion of the rail on a gauge side; anda protrusion on the second wall section adjacent the rail base, which engages a groove on the flangeway former for positioning the flangeway former when the flangeway former abuts the rail boot. 13. The rail boot of claim 12, wherein the protrusion is generally trapazoidal in cross-sectional profile. 14. A spacer for use in association with a rail, a rail boot, and a flangeway former comprising: a strip comprising three contiguous channel segments and an arm at each end of the strip,wherein the first and third channel segments are oriented in the same direction and the second channel segment is situated between the first and third channel segments and is oriented in a direction opposite to the first and third channel segments; andwherein the arm at one end of the strip secures the top of the rail boot on a field side of the rail when the spacer is installed; andwherein the arm at the other end of the strip secures the top of the flangeway former on a gauge side of the rail when the spacer is installed. 15. A rail boot retaining clip comprising a first section in the general shape of an end of a rail base of a rail that, when employed, forms a rail boot around the end of the rail base of the rail, and a bracket that is contiguous with the first section and is configured to attach to a fastener in a manner that holds the rail boot clip tightly against the rail boot. 16. The rail boot retaining clip of claim 15 further comprising an arm extending from an upper portion of the first section to assist in retaining a flangeway former. 17. A rail boot retaining clip system comprising: a first rail boot retaining clips according to claim 15 that, when employed, forms a rail boot around the field side of a rail base of a rail,a second rail boot retaining clip comprising a first section in the general shape of an end of a rail base of a rail that, when employed, forms a rail boot around the gauge side of the rail base of the rail, and a bracket that is contiguous with the first section and is configured to attach to a fastener in a manner that holds the rail boot clip tightly against the rail boot, and further comprising an arm extending from an upper portion of the first section to assist in retaining a flangeway former,and a fastener that engage the brackets of the first and second rail boot retaining clips to hold said clips tightly against the rail boot.
